Precision Fabricators (PFL) manufactures stainless-steel cylinders, canisters, process equipment, bubblers, ampoules, pressure and reaction vessels for a wide range of purposes. Products may be DOT-certified, bolt-top, clamp top (triclover) or designed to ASME standards. PFL bubblers are often specified for CVD/ALD processes, ultra-high purity gases, cryogenic applications, pharmaceutical and biologic materials, petrochemicals and hydrogenation processes. Our facilities have class 10,000 and class 100 cleanroom environments to ensure delivery of clean and ready-to-fill vessels, manifolds and piping. Precision Fabricators is DOT approved to recertify previously used cylinders and maintains new cylinders in stock for rapid delivery in a range of common sizes. Custom sizes are also available.
PFL also offers a line of reaction vessels and reactors as alternatives to Parr® Vessels (KF top, CF top, screw top and custom), and provides a choice of o-rings, seals, clamps, fittings and valves to deliver products safe from cryogenic temperatures to high temperatures and pressures. Products receive 100% testing using nitrogen-pressure and helium-leak tests and may be packaged in our class 100 cleanroom and/or our nitrogen bagging area. Precision Fabricators provides engineering design services, an ISO 9001-approved quality system, rapid response, on-time delivery and 7-day/week operations to meet any need.

PFL also offers DOT Recertification / Volumetric Expansion / Hydrostatic Pressure Testing for DOT cylinders 4B, 4BA, 4BW, 3A, Medical, Scuba, and Industrial cylinders up to 13.75" in diameter (350mm). We are serving former customers of Andonian Cryogenics. Call for details.
