Supreme Compression Repair Coupling 25mm


A very high quality compression water fitting that is suitable for use with drinking water. 

Technical specification


Top quality raw materials are used this makes the fittings very reliable and resistant

Body, Nuts and Thrust Ring

Virgin Polypropylene (PP-B), high mechanical resistance and thermal stability UV resistant

Grip Ring

Copolymer polacetal resin white in colour ( not sure what this is about but think it must grip the pipe really well)

Conical Gasket

Rubber NBR. hardness 70sh black in colour


WRC, WRAS (16 bar only)

How to use

1.  Remove the blue nut and place on the pipe. 

2.  Remove the white grip ring and slide on to pipe

3.  Make sure that the cut on the end of the pipe is square and that any burs have been removed.  For large fittings a bevel on the outside edge will aid fitting

4.  Coat the gasket which is inside the fitting with silicon lubricant or similar

5.  Push the pipe inside the fitting.  Push the pipe beyond the gasket as far as you can go to allow more pipe to work with in confined spaces.

6  Now slide the white grip ring up the pipe and inside the pipe.

7.  Slide the blue nut down the pipe and tighten to hand tight.  Add another quarter turn using a strap or similar.  Larger fittings may need more as the threads are quite stiff. 

8.  Pressurize the pipe and fittings before covering to make sure that the fittings have been fitted correctly

For threaded fittings use gas grade PTFE to for a seal between the threads again if you are unsure than please call us for more information
