Tighten these nuts onto high-pressure compression sleeves and fittings to create a strong seal on stainless steel tubing. Made from 316 stainless steel, they won’t corrode from water, chemicals, or salt spray. These nuts meet ISO 8434 (formerly DIN 2353), which is an international standard for tube fitting dimensions and materials.

Nuts for High-Pressure Compression Fittings for Steel Tubing
- For Use With: Hydraulic Fluid
- Temperature Range: -75° to 750° F
- Tubing: Use with seamless steel
- Specifications Met: ISO 8434, DIN 2353
Pair these nuts with compression sleeves and high-pressure fittings. They withstand about twice as much pressure as nuts for standard compression fittings, so they’re good for hydraulic power applications. As you tighten the nut, the fitting’s sleeve, or ferrule, bites into the steel tubing and creates a strong seal. All meet ISO 8434 (formerly DIN 2353), which is an international standard for tube fitting pressures.
