Plastic Quick-Clamp Sanitary Fittings for Stainless Steel Tubing
- For Use With: Dairy, Water
- Temperature Range: -40° to 170° F, except gaskets (see table)
- Tubing: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM A270
- Specifications Met: 3-A Certified 62-02, FDA Compliant 21 CFR 177.2510
Made of PVDF (Kynar), these fittings are lightweight compared to metal quick-clamp fittings. The clamp separates into three pieces and threads over the quick-clamp ends of the fittings to create an access point in a line. Tighten the clamp with a spanner wrench (sold separately) for a secure seal.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Quick-Clamp High-Vacuum Fittings for Stainless Steel Tubing
- For Use With:
Fittings with Gasket End: Air, Argon, Helium, Nitrogen
All Other Fittings: Air - Temperature Range: 0° to 300° F
- Tubing: Use with 304/304L or 316/316L stainless steel
- Specifications Met: ISO 2861
Instead of a gasket, these fittings have a special ring that is designed for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases. Also known as KF, QF, and NW fittings, they are the most common type of connection in high-vacuum systems. Connect with a clamp and another quick-clamp fitting for fast, easy access to your line. To use fittings in pressure applications, use a pressure-rated ring (sold separately).
304 stainless steel fittings have very good corrosion resistance.
Note: To complete a connection, you’ll need two quick-clamp fittings, a ring, and a clamp (all sold separately).
Fittings with gasket end connect with a stainless steel gasket (sold separately) instead of a rubber one, generating fewer particles to create a stronger high-vacuum seal. Their interior is ultra-smooth to attract fewer contaminants. These adapters are commonly used to add gases such as helium, argon, or nitrogen into high-vacuum systems. Also known as VCR fittings.

Ultra-High-Polish Gasket Fittings for Stainless Steel Tubing
- For Use With: Argon, Helium, Nitrogen
- Temperature Range: -420° to 1000° F
- Tubing: Use with 316/316L stainless steel
- Compatible With: Swagelok® VCR
The 15 Ra finish on the interior of these fittings creates an ultra-smooth surface. Also known as ultra-high-purity fittings, they are packed in a Class 100 clean room to prevent contamination. They are commonly used in semiconductor applications. Fittings use a metal gasket (sold separately), which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Fittings are 316 stainless steel for excellent corrosion resistance.

Fittings use a metal gasket, which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Two anti-torque rings further reduce particle generation by preventing the metal gasket from twisting and loosening. Fittings are 316 stainless steel for excellent corrosion resistance.
