Low-Pressure Stainless Steel Threaded Pipe Fittings
Use these fittings in a low-pressure pipe line.
Fittings that meet ANSI/MSS SP-114 adhere to high-quality standards for heat treating, material thickness, and marking. 304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration.
NPTF (Dryseal) threads and NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.

Low-Pressure Iron and Steel Threaded Pipe Fittings
Use these fittings for low-pressure applications in noncorrosive environments.
Adapters for tanks create an inlet or outlet connection on the surface of any tank, pressure vessel, or drum. Adapters with weld end allow for a permanent connection. Adapters with extension fit tightly into the hole, which keeps the fitting steady during welding.

Low-Pressure Aluminum Threaded Pipe Fittings
In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a 1/4-turn past hand tight.
Adapters for tanks weld onto the surface of any tank, pressure vessel, or drum to create a permanent inlet or outlet connection. Adapters with extended lip fit tightly into the hole, which keeps the fitting steady during welding.

Quick-Clamp High-Vacuum Fittings for Stainless Steel Tubing
- For Use With:
Fittings with Gasket End: Air, Argon, Helium, Nitrogen
All Other Fittings: Air - Specifications Met: ISO 2861
Instead of a gasket, these fittings have a metal-reinforced O-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). Made of 304 stainless steel, these 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).

Quick-Clamp High-Vacuum Fittings for Aluminum Tubing
- For Use With: Air
- Specifications Met: ISO 2861
For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. To form a complete connection, pair two adapters with a clamp and a ring (all sold separately). Made of aluminum, these fittings are lightweight and resist corrosion. This and the airtight seal make them a good choice for vacuum coating, heat treating, or leak testing. Also known as KF, QF, and NW fittings.
