How to choose Elbow bulkhead unions

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

Technical data

⚡Tube 6 L to 42 L - light series for standard pressures, heavy series from 6 S up to 38 S for higher load.

⚡Bulkhead thread M 12x1,5 to M 52x2 - the through thread follows the tube size, panel thickness being taken up by the lock nut.

⚡90 degree turn - the line changes direction right behind the panel, saving room for a further pipe bend.

⚡Two materials - zinc plated steel for dry surroundings, stainless steel 1.4571 against moisture, salt or aggressive media.

⚡Supply form - complete, or as a body without nut plus cutting ring for prepared tube ends.

Applications

Bulkhead unions sit in housing panels, control cabinets, machine covers, tank walls. They hold the line mechanically, keeping pull as well as vibration away from the pipework behind. The elbow shape is chosen where little room remains for an extra bend inside. Sizes from 25 S upwards serve main lines, small sizes from 6 L carry control lines.
