How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.
