Compression Fittings for Steel Tubing
- For Use With: Inch: Air, Hydraulic Fluid, Water
Metric: Hydraulic Fluid - Tubing: Inch: Use with welded steel
Metric: Use with seamless steel - Specifications Met: Inch: SAE J514
Metric: ISO 8434, DIN 2353
A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless and bite fittings.
Zinc-plated steel fittings have fair corrosion resistance.
ISO 8434 (formerly DIN 2353) fittings meet international standards for tube fitting pressures.
