Sanitary & Hygienic Fittings & Tubing — Triplex Sales
Sanitary & Hygienic Fittings & Tubing

Fittings built for clean processes.

Triplex Sales stocks the full range of stainless sanitary fittings and tubing used across food & beverage, dairy, brewing, pharma, and industrial processing — from everyday Tri-Clamp ferrules to ASME-BPE biopharm components and super-austenitic corrosion-resistant alloys.

We carry five brand partners: Dixon Sanitary, Wayland Industries, the VNE family (including MaxPure and MaxCore), RathGibson, and United Industries. That coverage means the right fitting or tubing for the application — not just what's on the shelf.

Size Range 1/4" - 12"
Materials 304 · 316L · 6Mo
Standards 3-A · ASME-BPE
01 — Brands

Five brand partners, one supplier.

Each brand solves a different slice of the sanitary market. Dixon and Wayland cover the broadest fitting range; the VNE family adds U.S.-made dairy, food, and biopharm fittings — with MaxPure and MaxCore at the top of the spec ladder. RathGibson and United Industries round out the program with sanitary tubing that meets or exceeds ASTM A270 S2 and 3-A.

02 — Fitting Types

The core library of sanitary fittings.

Most hygienic process systems are assembled from a small vocabulary of standardized parts. Here's the shorthand — and which of our brands carry each.

Sanitary Tri-Clamp heavy-duty clamp

Clamps

Single-pin, double-pin, three-segment, bolted, toggle, T-bolt, and dairy clamps — the mechanical hardware that holds Tri-Clamp unions together.

Carried by: Dixon · Wayland · VNE
Sanitary weld ferrule

Ferrules

Short-weld, long-weld, reducing, roll-on, and schedule 5/10 ferrules — the weld-end half of a clamp connection that terminates tube or pipe.

Carried by: All fitting brands
Sanitary 90 degree clamp-end elbow

Elbows

45°, 90°, long-sweep, U-bends, and reducing elbows in clamp × clamp, weld × weld, or mixed-end configurations.

Carried by: All fitting brands
Sanitary weld-end tee fitting

Tees & Crosses

Equal and reducing tees, true-Y's, laterals, and 4-way crosses — for branch connections, sampling, and manifold construction.

Carried by: All fitting brands

03 — Connection Styles

Every connection standard used in hygienic processing.

The connection style determines how a fitting mates: which gasket it takes, what service pressure it holds, how cleanable it is, and whether it meets 3-A or ASME-BPE. We stock the full spectrum.

Style
What it is
Typical use
Stocked by
Tri-Clamp (Clamp)Most common · 3-A
Two grooved ferrules compressed against a gasket by a 360° clamp ring. Fast tear-down for CIP and changeovers. Service pressure 300-1500 PSI depending on clamp style and size.
Food & beverage, dairy, brewing, general sanitary — any line with frequent disassembly.
DixonWaylandVNEMaxPureMaxCore
Bevel SeatIDF / ISS · legacy dairy
Threaded-nut union with mating beveled male and female ferrules and a sanitary gasket. The pre-clamp industry standard; still dominant in older dairy plants.
Legacy dairy, some brewing, equipment retrofits where matching existing plant is required.
DixonWaylandVNE
I-Line / Q-LineCherry-Burrell
Interlocking ferrules with a positioning lug that prevents misassembly and ensures consistent gasket compression. Common in long-crimp sanitary installations.
Dairy, brewing, process plants built around Cherry-Burrell equipment.
DixonWaylandVNE
John PerryAcme-thread dairy
Acme-threaded union with a square-shoulder gasket recess. Higher pressure than bevel seat; found on older milk-processing and transfer systems.
Dairy, tanker / transport lines, equipment built pre-1990.
DixonWaylandVNE
Butt WeldPolished · unpolished
Fittings welded directly tube-to-tube with no mechanical seal. Maximum cleanability — no gasket traps — but requires breaking the weld for service. Polished to 20/32 Ra for hygienic runs.
Fixed process piping, CIP/SIP loops, biopharm, any line where teardown is rare.
DixonWaylandVNEMaxPureMaxCore
European: DIN · SMS · RJTMetric / British
European sanitary unions — DIN (German), SMS (Swedish), RJT (British dairy). Each has its own thread, seat geometry, and gasket profile. Critical for imported equipment.
European process equipment, overseas OEM integrations, multinational plants.
DixonWaylandVNE
ASME-BPEBiopharm · high-purity
Dimensional and surface-finish standard for bioprocess equipment. Tighter tolerances than 3-A, controlled sulfur for orbital welding, documented Ra, and full traceability per DT-3-1 / SF-2.4-1.
Pharmaceutical, biotech, personal care, cell & gene therapy — anywhere process validation is required.
DixonMaxPureMaxCore
Vacuum: KF / ISOLab & vacuum service
KF (small-bore quick-flange) and ISO (bolted flange) fittings for vacuum service, including rings, bellows, clamps, and weld fittings.
Vacuum pumping stations, lab process equipment, R&D and pilot lines.

04 — Materials & Finishes

Spec the right alloy and surface for the service.

The difference between a five-year and a twenty-year service life is almost always in the alloy selection and surface preparation. Here's what drives the call.

Alloys we stock

  • T304 / 304L Workhorse sanitary stainless. 18Cr / 8Ni. Food contact, dairy, brewing, water — where chlorides are low and cost matters.
  • T316L Default for sanitary service. Adds 2-3% Mo for chloride resistance. Specified for most new builds and all BPE applications.
  • 316L low-S MaxPure biopharm. Controlled sulfur 0.005 - 0.017% for repeatable automatic orbital welding. ASME-BPE required.
  • 904L Super-austenitic. ~4.5% Mo, higher Ni. PREN ~36. Upgrade from 316L where chloride-induced pitting is a problem.
  • 6Mo (N08367) MaxCore 6Mo. PREN ~46. Seawater, high-chloride process, pharma chloride cleans, aggressive CIP chemistries.
  • Alloy 22 (N06022) Nickel-base (Hastelloy C22® eq). For the most aggressive chemistries — mixed acids, hot chlorides, low-pH reactive services.

Surface finishes

  • No. 1 / SF0 Unpolished. Mill finish. Non-product-contact or jacketed service.
  • No. 3 ID polish only. 150-grit interior; mill OD. Internal cleanability without the OD cost.
  • No. 4 / 32 Ra Standard sanitary. ~32 μin Ra. Default 3-A finish for food & beverage.
  • No. 7 / 20 Ra Polished ID & OD. ~20 μin Ra. Wayland / RathGibson A270 tubing standard; most new sanitary builds.
  • MP (SF1) ASME-BPE Mechanically Polished. ≤20 μin Ra. Standard BPE product-contact surface.
  • EP (SF4) Electropolished. ≤15 μin Ra. Passive, ultra-smooth, chromium-enriched layer. Biopharm gold standard.
  • Passivation ASTM A967 / ASME-BPE. Acid treatment that restores the passive chromium-oxide layer. Standard on MaxPure and MaxCore.
