Frequently Asked Questions

What is the LEGRIS 180° return pipe elbow used for?

The LEGRIS 180° return pipe elbow is used to reverse fluid flow direction in high-pressure hydraulic or pneumatic systems. It connects two female BSPP threaded ports in tight spaces, common in industrial machinery, process lines, and fluid power applications requiring a compact U-turn configuration.

What are the specifications of the LEGRIS 0155 21 21 elbow?

The LEGRIS 0155 21 21 is a metal pipe elbow with 180° return, 1/2 in x 1/2 in female BSPP threaded connections. Maximum operating pressure is 1,000 psi. It is designed for high-pressure threaded pipe systems and is part of the LEGRIS threaded high-pressure pipe fittings range.

Where to buy LEGRIS pipe fittings worldwide?

3G Electric supplies LEGRIS pipe fittings worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source and deliver genuine LEGRIS components like the 0155 21 21 elbow to any location. Contact us for a quote and delivery options.

How to install a LEGRIS 180° return elbow?

Install the LEGRIS 180° return elbow by applying thread sealant to the male BSPP threads, then hand-tighten into both female ports. Use a wrench on the hex flats to finalise, avoiding over-torque. Ensure the elbow is oriented correctly for the return flow path before tightening fully.
