Screwed elbow 1/2x16 with external thread

Product detailed description

Screwed elbow 1/2x16 with external thread - a screw-type coupling that requires no pressing, for plastic-aluminium (PEX-AL-PEX) pipe (16x2 mm) for water or heating.

This 90° elbow is a great choice whenever you need a reliable joint on PEX-AL-PEX pipe without investing in expensive pressing tools - just an ordinary wrench and the joint is done in a few minutes.

What makes this coupling stand out

• No special tools needed - unlike press-fit systems you don't need expensive pressing jaws, just an open-end wrench.
• Detachable joint - if needed (pipework modification, repair) the joint can be disassembled and reassembled again, which is not possible with press-fit joints.
• Proven tightness - 2 rubber sealing rings (EPDM) and a brass clamping ring ensure a reliable seal even after repeated tightening.
• Universal use - suitable for underfloor heating, drinking water pipework, and radiator pipework.

Step-by-step installation

1. Cut the PEX-AL-PEX pipe perpendicular to its axis and use a calibrating tool to shape its end into a perfectly round form (this also removes any burr left by the cut).
2. Slide the union nut onto the pipe, followed by the clamping ring.
3. Push the pipe fully home into the body of the coupling.
4. Tighten the union nut with an open-end wrench - do not overtighten, it is enough to tighten the joint to firm resistance.
5. After filling the system, check the joint for any leaks and, if necessary, tighten slightly more.

Frequently asked questions

• Can this coupling be used repeatedly? Yes, unlike press-fit joints it can be disassembled and reassembled, which is also ideal for minor repairs or changes to the pipework.
• Do I need special tools? No, an ordinary wrench is enough (an open-end wrench).
• Is it suitable for gas as well? No - for gas pipework always use only components certified for that purpose.
