Threaded Fittings

Steel Fittings

Riegler steel fittings are threaded connecting elements made of steel for piping, represented here by pipe double nipples with male thread on both ends (male/male). The items follow connection sizes such as R 1/4 and R 3/8 in graded overall lengths.

The range comprises more than 140 items. Steel as a material offers higher mechanical strength than brass and suits piping systems with corresponding pressure and load requirements.

Buying guide

How to choose Steel Fittings

What matters when choosing: properties, comparison and typical applications.

Typical Applications

Steel fittings are used in the piping of compressed-air, water and general industrial lines where higher mechanical strength is required. The double nipples with male thread on both ends join female-threaded ports, and the graded lengths bridge design distances between components.
