Smooth-Bore Seamless Stainless Steel Tubing
Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
304 stainless steel has very good corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.

Miniature Stainless Steel Tubing
Also known as hypodermic or needle tubing, this tubing has thin walls and is made to tight tolerances for use in precision applications. It is welded with a smoothed weld bead on the inside to reduce particle buildup. Tubing connects by welding. To cut this tubing, you can use abrasive cutoff wheels and deburring tools or electrolytic cutting tools (not included).
304 stainless steel has very good corrosion resistance.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- Temperature Range: See Gaskets
The smooth finish inside these fittings makes it easy to remove product residue. Also known as aseptic and tri-clamp fittings, they connect with a gasket, a clamp, and another quick-clamp fitting for a fast and easy way to access your line. The pressure rating of the fitting will vary depending on the clamp you choose, and the temperature rating will vary based on the gasket material you choose.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
3-A certified fittings comply with sanitary standards.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Recessed Nut, Hole for
Lockout, and 2-Pin Hinge
Clamps with wing nut tighten by hand. Clamps with bolt tighten with a wrench. They handle higher pressures than wing-nut clamps for a stronger, more secure hold.

Buna-N gaskets are oil resistant. EPDM gaskets resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets stand up to fuel, oil, and acid condensates. PTFE gaskets withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.

Through-Wall Fittings for High-Vacuum Chambers
- For Use With: See table
- Environment Temperature Range: 32° to 300° F
- Process Temperature Range: -325° to 995° F
- Tubing: Use with 304/304L or 316/316L stainless steel
- Specifications Met: See table
Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs. Because they form a tight seal on chamber walls, they are often used in coating, cooling, and leak-testing applications where negative pressure (vacuum) must be maintained. These fittings are ready to install and include high-vacuum fittings, metal tubing, and Yor-lok tube fittings. On each end, the Yor-lok fittings include a nut and two sleeves that grip your system’s stainless steel tubing. The entire assembly is stainless steel, so it resists rusting. These fittings are not for use in pressure applications.
Quick-clamp fittings meet ISO 2861, which specifies the dimensions of quick-clamp high-vacuum fittings, clamps, and rings to ensure vacuum tightness. These fittings require a clamp and ring (each sold separately) to complete the connection.
Flanged fittings require a gasket and bolt kit (each sold separately) to complete the connection.

- For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
- Temperature Range: Neoprene Rubber Gaskets: -20° to 190° F
Silicone Rubber Gaskets: -100° to 500° F - Tubing: Use with steel
Bolt clamps have a stainless steel strip that provides an escape route for electrostatic buildup when used in a fully-grounded system. They have fair corrosion resistance.
