Data Center Cooling Sanitary Fittings Supply | Triplex Sales
Data Center Cooling · Sanitary Fittings Supply

Sanitary fittings supply for data center cooling.

Triplex Sales supplies the sanitary fittings, clamps, gaskets, and stainless tubing behind facility water, technology cooling, direct-to-chip, and immersion systems. Match the specification across trusted manufacturers and consolidate the wet-side BOM without chasing each line item separately.

From 304 and 316L clamp and weld fittings to A270 tubing and specialty alloys, we help teams balance specification, availability, lead time, and total project value. Pumps, valves, supports, and related components can stay on the same quote and one PO.

Loop Coverage FWS · TCS · D2C
Line Sizes 1/4" - 12"
Materials 304 · 316L · 6Mo
01 — Loop Architecture

Sanitary fittings first. The rest of the wet-side BOM on one PO.

Most data center cooling builds create a fittings problem before they create a pump problem: many line items, multiple specifications, and availability that shifts by manufacturer. Triplex brings clamp, weld, threaded, BPE, tubing, gasket, valve, pump, and support options into one sourcing conversation.

Loop 1

Facility Water System

FWS · Primary · Cooling Tower → CDU

The big-bore side. Treated water — often with glycol and corrosion inhibitor — loops from the cooling tower or chiller plant to the facility-side of every CDU. Runs 6"-12" mains, carbon steel or 304 stainless, with butterfly isolation at every branch and tap.

Because fluid chemistry is controlled by plant chemistry, not by IT, this loop tolerates harder materials and less-polished surfaces. But reliability is non-negotiable: any FWS failure cascades into a thermal event.

What we ship Centrifugal pumps · Butterfly valves · Check valves · Y-strainers · 304 weld fittings · Carbon-steel hangers · EPDM gaskets
Loop 2

Technology Cooling System

TCS · Secondary · CDU → Rack / Row

Between the CDU and the row manifold. Typically a 25% propylene-glycol / water mix or treated DI water, held at precise temperature and flow. Cleanliness matters here — any debris makes it to the cold plate.

Lines are usually 2"-6" 304/316L stainless, either welded or Tri-Clamp, with isolation ball valves at every rack drop and pressure/flow instrumentation throughout. Polished ID tubing (20/32 Ra) is standard on new hyperscale builds.

What we ship Sanitary centrifugal pumps · Ball & diaphragm valves · 316L weld fittings · A270 polished tubing · EPDM / FKM gaskets · Stainless hangers
Loop 3

Direct-to-Chip & Immersion

D2C · Rack / Tank Side

Inside the rack. Cold-plate and immersion systems run on high-purity water, propylene glycol, or engineered dielectric fluids (single- or two-phase). Flow paths are smaller — 1/4" to 1" — and tolerance for particulate is measured in microns.

Tri-Clamp, quick-disconnect, and compression-fit manifolds predominate. Gasket choice is driven by fluid compatibility: EPDM for water/glycol, FKM for fluorinated dielectrics, PTFE for broad chemical service.

What we ship Sanitary centrifugal pumps · Rotary lobe pumps · Compact ball valves · Sanitary clamp fittings · BPE-finish tubing · FKM / PTFE gaskets · Compact hangers
02 — Product Program

03 — Cooling Technologies

Every architecture the market is building around.

The cooling-technology stack is in active flux. Air still handles the majority of installed capacity, but every new AI and HPC buildout is liquid-first. Here's how each approach maps to our component program.

Technology
How it works
Typical fluid
Components we ship
Air · CRAC / CRAHLegacy · ≤15 kW/rack
Perimeter or row-based computer-room air conditioning units with chilled-water or DX coils. Still dominates installed capacity below 15 kW/rack. Facility-water side of every CRAH is a liquid system.
Chilled water (FWS side)
PumpsButterflyStrainersWeld fittings
Rear-Door Heat ExchangersRDHx · 20-75 kW/rack
Liquid-cooled coil mounted on the back of a standard rack. Fans pull hot exhaust air through the coil, rejecting heat to chilled water. Retrofit-friendly — no raised floor or containment changes required.
Chilled water (FWS)
PumpsBall valvesFlex connectors316L fittings
Direct-to-Chip (Cold Plate)D2C · 50-150 kW/rack
Cold plates bonded to CPUs, GPUs, and memory with coolant circulated through microchannels. Now the default architecture for NVIDIA H100/H200/GB200 clusters and equivalent AMD/Intel platforms.
PG-25 water or DI water
Sanitary pumpsBall valvesTri-ClampA270 tubingEPDM gaskets
Single-Phase Immersion1PIC · 50-200 kW/rack
Servers submerged in a dielectric fluid bath. Heat removed by pumping warm fluid through an external heat exchanger. No phase change; lowest-complexity immersion approach.
Mineral oil, synthetic, Novec-series
Ball valves316L fittingsFKM gasketsSpecialty tubing
Two-Phase Immersion2PIC · 100-250 kW/rack
Engineered fluid boils at chip surface; vapor rises to a water-cooled condenser and returns as liquid. Highest heat-flux architecture; tighter tolerances on vapor-path sealing.
Engineered fluorocarbon

04 — Materials & Fluids

Spec the alloy and the elastomer for the fluid.

Datacenter cooling systems run 24/7 for 15+ years. Small misalignment between fluid chemistry and material choice shows up as pitting, stress-corrosion cracking, or elastomer swell three to five years in — usually under load, always expensive. Here's how we spec it.

Alloys in the loop

  • Carbon Steel FWS mains only. Low cost for large-diameter facility-water headers where chemistry is controlled. Requires inhibitor package and annual testing.
  • T304 / 304L General-purpose stainless. FWS mains, cooling-tower risers, makeup-water piping where chlorides are below ~200 ppm.
  • T316L Default for TCS and D2C. Added Mo resists chlorides and inhibitor breakdown products. Specified on nearly every hyperscale TCS loop.
  • 316L low-S (BPE) Cleanroom DC builds. Controlled sulfur for repeatable orbital welding. Used on D2C loops where surface cleanliness is part of the service spec.
  • 6Mo (UNS N08367) High-chloride makeup water. Coastal sites, reclaimed water, and once-through seawater cooling. PREN ~46 vs. 316L's 27.
  • Copper / Brass Cold-plate side only. Inside the server; not in the facility or TCS piping. Fluid chemistry must protect copper — no ammonia, controlled pH.

Fluids & compatible elastomers

  • Treated Water FWS default. City or well water with corrosion inhibitor, biocide, pH adjuster. Gaskets: EPDM.
  • PG-25 / PG-30 TCS standard. 25-30% propylene glycol / water mix for freeze protection and corrosion control. Gaskets: EPDM.
  • Deionized Water Advanced D2C. High-purity water with controlled conductivity. Aggressive to many metals — 316L minimum. Gaskets: EPDM or PTFE.
  • Mineral / Synthetic Oil 1P immersion. Hydrocarbon or engineered synthetic dielectric. Gaskets: FKM (Viton®), NOT EPDM (swells).
  • Fluorinated Dielectric 2P immersion. Engineered fluorocarbon (Novec-series, etc.). Gaskets: PTFE or FFKM; specialty elastomers required.
  • Glycol Blends · Custom OEM-specified. Some CDU vendors ship a proprietary fluid. Always confirm elastomer compatibility against the vendor's data sheet before ordering gaskets.

08 — Frequently Asked

Answers for engineers, PMs, and mechanical contractors.

The questions that come up most on datacenter cooling projects. Anything not here — ask us and we'll route it to the specialist who owns the category.

What cooling loops does Triplex Sales supply components for?

All three — the Facility Water System (FWS), Technology Cooling System (TCS), and rack-side direct-to-chip or immersion loops. Each loop has its own alloy, surface finish, and gasket requirements, and we stock across the full spectrum from carbon steel FWS mains through 316L electropolished TCS tubing.

What line-size range do you stock?

1/4" to 24" depending on the component. 1/4" to 12" covers the sanitary fitting and tubing lineup; butterfly valves and large-bore pipe run to 24" for FWS mains and cooling-tower risers. Full reducing-combination coverage across the range.

Do you supply complete wet-side BOMs for CDU or cooling skid projects?

Yes. Send a bill of materials and we come back with a line-item quote covering pumps, valves, fittings, tubing, gaskets, and hangers — with lead times and any alloy or finish callouts worth reviewing before ordering.

What traceability documentation is available on datacenter orders?

EN 10204-3.1 Mill Test Reports on every stainless heat. ISO 9001 quality systems on all fitting, pump, and valve lines. ASME-BPE documentation on biopharm-spec components. FDA-compliant gasket certs where required.

Do you stock alloys beyond 304 and 316L for high-chloride datacenter service?

Yes. 6Mo (UNS N08367, PREN ~46) for high-chloride cooling-tower and seawater service, 904L for super-austenitic pitting resistance, and Alloy 22 (Hastelloy C22® equivalent) for the most aggressive chemistries — coastal sites, reclaimed makeup water, or aggressive CIP loops.

How does your datacenter cooling program differ from your hygienic and food-and-beverage program?

Much of the stainless fitting and tubing lineup overlaps — sanitary cleanliness matters on TCS and D2C loops just like it does in food, dairy, and biopharm. Differences appear on the facility-water side (carbon-steel mains, large-bore butterfly valves, inhibitor chemistry) and in elastomer selection — FKM and PTFE are required for dielectric-fluid immersion service, not EPDM.

How will the upcoming sanitary fittings quote tool help?

It is being built to compare sourcing paths across the Triplex sanitary fittings offering, so pricing, availability, and lead-time options can be reviewed together. That reduces quote time and helps identify a better overall fit for the project without chasing manufacturers one by one.

Next Step

Send the fittings BOM. We'll help find the best path.

Clamp and weld fittings, tubing, gaskets, and related wet-side components across 304, 316L, and specialty alloys. We'll review specification, pricing, availability, and lead-time options together, then build the quote around what matters most to the project.
