How to choose Male stud elbows, R/G thread

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

Technical data

⚡Threads R 1/8" to G 1-1/2" - tapered R threads for self sealing stud joints, large G threads from G 3/4" upwards for main ports.

⚡Tube 4 LL to 42 L - very light series from 4 LL (M8x1), light series up to 42 L (M52x2), heavy series up to 38 S (M52x2).

⚡NC clamping ring 1.4571 - the NC ring grips the tube without a deep cut, which suits thin walled tube.

⚡90 degree bend - the turn sits right at the thread port, so a separate pipe bend is dropped.

⚡Materials - zinc plated steel, stainless steel 1.4571, plus variants supplied without nut or cutting ring.

Applications

These fittings connect tube lines to pumps, cylinders, filters, manifolds carrying an inch sized female port. Small sizes from 4 LL serve gauge as well as control lines, sizes from 25 S upwards carry pressure lines of high flow. Where the port sits close to a housing, the 90 degree bend takes the line parallel to the wall at once.
