Quick Trade Summary: Copper M-Profile Press Fit Straight Coupling
MEP Stock supplies heavy-duty copper M-profile press fit straight couplings engineered for inline joining of BS EN 1057 copper pipe. Features an internal pass-through central pipe stop and factory-lubricated black EPDM O-rings for potable water and central heating systems up to 16 bar.
M-Profile Straight Couplings for Rapid In-Line Mechanical Jointing
Joining straight copper pipe runs in commercial risers, ceiling voids, and domestic heating repipes is made fast, clean, and flame-free with our M-profile copper press straight couplings. Conforming to BS EN 1254-7, the fitting provides a permanent mechanical seal without hot-works insurance permits or fire-watch delays.
Engineering Specifications & Material Standards
| Parameter | Specification Standard |
|---|---|
| Fitting Material | Deoxidised High Phosphorus Copper CW024A / Cu-DHP (BS EN 1254-7) |
| Pipe Compatibility | BS EN 1057 (R250 Half-Hard / R290 Hard Table X) |
| Sealing Element | Factory-Lubricated Black EPDM (Potable Water & Heating) |
| Press Profile | M-Profile Press Jaws (Rothenberger, Milwaukee, Novopress, REMS, Klauke) |
| Pressure Rating | Max 16 bar (PN16) |
| Temperature Range | -20°C to +110°C (-4°F to 230°F) |
| Safety Feature | Leak-Before-Press (LBP) bypass channel identifies unpressed joints |
Step-by-Step Installation Protocol
- Square Cut: Cut copper pipe cleanly at 90° using a rotary wheel cutter.
- Deburr Inside & Out: Ream both inner and outer edges thoroughly; sharp burrs damage the EPDM seal.
- Mark Depth: Measure socket depth to the center stop and mark clearly on both pipes.
- Insert to Stop: Slide coupling over pipe until it seats against the internal central stop.
- Mechanical Press: Mount M-profile jaw square on the bead and complete the full crimp cycle on both collars.
Frequently Asked Questions: Copper M Profile Press Fit Water Straight Coupling
What is the difference between this standard coupling and a slip coupling?
A standard coupling has an internal center stop; a slip coupling has no stop. Standard couplings are used for joining new lengths of pipe where the tube bottoms out against the internal stop. Slip couplings (repair sockets) can slide completely along a copper pipe to repair bursts or cut out damaged sections.
What press jaw profile is required for this straight coupling?
This fitting strictly requires M-Profile press jaws. Standard UK press tools from Rothenberger, Milwaukee, Novopress, Klauke, and REMS fitted with M-contour jaws will execute the certified hexagonal deformation.
Can I press this coupling on wet or dripping copper pipe?
Yes, press fittings can be pressed on wet pipes with residual water present. Unlike capillary soldering, which requires bone-dry pipe to melt solder, mechanical pressing relies on radial compression of the EPDM seal.
Is this coupling WRAS approved for drinking water?
Yes, fully WRAS approved for hot and cold wholesome drinking water. under the Water Supply (Water Fittings) Regulations 1999.
What is the minimum pipe clearance between two straight couplings?
Maintain at least 10mm to 15mm clearance between fitting collars. on 15mm/22mm pipe, and 20mm on larger sizes to allow press jaws to seat squarely.
How does the Leak-Before-Press (LBP) feature work?
The EPDM O-ring features a bypass channel that leaks fluid at 0.1 to 3 bar if unpressed. ensuring instant detection during testing before system commissioning.
