Quick Trade Summary: Copper M-Profile Press Fit Water Tap Connector
MEP Stock supplies professional copper M-profile press fit straight tap connectors engineered for direct, flame-free connection between BS EN 1057 copper pipe and standard UK basin, bath, and sink tap tails. Fabricated from premium CW024A / DHP deoxidised copper with a heavy-duty DZR brass swivel nut, each fitting incorporates a factory-lubricated black EPDM press O-ring and a captive flat sealing washer. Delivers instant, leak-free mechanical jointing without blowtorches, flux contamination, or hot works insurance permits.
Precision Copper Press to Tap Tail Swivel Connections
Connecting rigid copper supply lines into vanity basin units, kitchen undermount sinks, and narrow bath panels is traditionally plagued by awkward blowtorch access and burnt cabinetry. Our M-Profile copper press tap connectors solve this by combining a cold mechanical press socket with a free-rotating, captive DZR brass swivel nut. Conforming strictly to BS EN 1254-7, the fitting creates a secure, non-rotational seal against the flat land of the tap tail, allowing plumbers to execute clean, professional sanitary installations in a fraction of the time.

Step-by-Step Installation & Sealing Protocol
- Verify Flat Tap Tail Face: Ensure the end of the male tap tail is clean, square, and free of burrs or scoring. The seal is created by compressing the internal washer against this flat face. Do not apply PTFE tape to the parallel threads.
- Square Tube Cut: Cut BS EN 1057 copper pipe cleanly at 90° using a rotary pipe wheel cutter. Avoid hacksaws to eliminate uneven faces.
- Internal & External Deburring: Thoroughly deburr both the inside and outside of the copper tube using a calibrated reamer. A sharp copper burr will tear the black EPDM O-ring during insertion.
- Mark Insertion Depth: Measure the socket depth and mark it onto the copper tube with a permanent marker.
- Tube Insertion: Push the copper tube into the press socket until it hits the internal stop and the insertion mark aligns flush with the socket rim.
- Mechanical Press: Mount calibrated M-profile jaws square onto the fitting bead. Complete a full machine crimp cycle.
- Engage Swivel Nut: Screw the brass swivel nut onto the tap tail by hand until it makes firm contact with the internal washer. Tighten an additional 1/4 to 1/2 turn using an adjustable spanner. Do not overtighten.
Frequently Asked Questions: Copper Press Fit Tap Connectors
Should I put PTFE tape on the tap tail threads when connecting this press tap connector?
No, never apply PTFE tape to the parallel BSP threads of a tap tail or swivel tap connector. Tap connectors seal entirely on the flat end face of the tap tail via the captive internal rubber or fiber washer—not on the spiral threads. Applying PTFE tape or jointing paste to the parallel threads prevents the swivel nut from tightening down squarely, which can pinch, twist, or misalign the sealing washer and guarantee a leak. Thread sealants are only for tapered BSP threads, never flat-faced swivel nuts.
What size tap connector do I need for standard UK basin and bath taps?
Basin taps require a 1/2" BSP swivel nut (typically on 15mm copper pipe); bath taps require a 3/4" BSP swivel nut (on 22mm or 15mm copper pipe). Standard UK wash hand basin pillar taps and monobloc tap tails use 1/2" BSP parallel threads (`15mm x 1/2"`), while high-flow bath filler taps, bath/shower mixers, and commercial laundry taps use larger 3/4" BSP threads (`22mm x 3/4"` or `15mm x 3/4"`). Always measure the tap tail diameter: 1/2" BSP threads measure ~21mm OD across the threads, while 3/4" BSP threads measure ~26.4mm OD.
Should I make the swivel nut connection or press the copper tube first?
Because the brass nut swivels independently, you can press the pipe either before or after hand-tightening to the tap. ned vanities, vanity units, or behind bath panels, installers often find it easiest to measure, dry-fit, and press the copper pipe into the connector socket on the bench or in open space, and then thread the captive brass swivel nut onto the tap tail with a spanner without any pipe twisting.
What type of sealing washer is used inside this tap connector?
It is equipped with a high-density, WRAS-approved flat elastomeric / rubber sealing washer suitable for hot and cold potable water. The washer is seated captive against the internal flat face of the copper spigot. Hand-tighten the swivel nut onto the tap tail until it makes solid contact with the washer, then give it a firm 1/4 to 1/2 turn with an adjustable spanner. Avoid extreme over-tightening, which can crush or distort the rubber washer.
What press jaw profile is required to crimp the press socket?
This tap connector strictly requires M-Profile press jaws. Calibrated pressing machines from Rothenberger, Milwaukee, Novopress, Klauke, and REMS fitted with M-contour jaws will execute the certified hexagonal deformation. Do not use V-profile or U-profile jaws on this fitting.
Can this tap connector be used on heating circuits or boilers?
Yes, provided the mating equipment features a flat-faced male BSP connection rated for the application. While primarily designed for sanitary basin and bath taps, the fitting is rated up to 16 bar (PN16) and temperatures from -20°C to +110°C, making it suitable for unvented cylinder connections, water heater inlets, and flat-faced manifold connections where a demountable swivel nut is preferred.
