Vibration-Resistant Compression Fittings for Steel Tubing
Threads with
Gasket and Washer
- For Use With: Cutting Oil, Diesel Fuel
- Temperature Range: -30° to 250° F
- Tubing: Use with seamless steel
- Specifications Met: DIN 3861
The sleeve (ferrule) in these fittings is made of rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal. Fittings are also known as flareless fittings. They are zinc-plated steel for fair corrosion resistance.
BSPP male threads have a gasket and washer to prevent leaks.
Metric male threads have either a gasket or a gasket and washer to prevent leaks.

O-Ring Face Seal Fittings for Steel Tubing
- For Use With: Air, Hydraulic Fluid
- Temperature Range: -30° to 250° F, except BSPP fittings are -20° to 230° F
- Tubing: Use with seamless steel
- Specifications Met: SAE J1453
A tube adapter sits flush against the flat face of the fitting so you can slide the tubing and fitting sideways to disconnect in cramped spaces. Fittings are also known as zero-clearance fittings. To install, weld a tube adapter to the tubing with a brazing ring (sold separately), then mate the tube adapter to the fitting and screw on the nut. As the nut is tightened, the tube adapter compresses the O-ring, creating a strong seal. Fittings are zinc-plated steel for fair corrosion resistance. Nuts and tube adapters are sold separately.
NPTF (Dryseal) threads are compatible with NPT threads.

Vibration-Resistant Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Lubricants, Mineral Oil, Water
- Temperature Range: -30° to 270° F, except fluoroelastomer sleeves are -15° to 450° F
- Tubing: Use with copper
The sleeve (ferrule) in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal. The sleeve aligns the tubing during installation. Fittings come with a nut and a sleeve. They are also known as flareless fittings. They are brass for good corrosion resistance.
