Quick Trade Summary: Brass Compression Stop End Pipe Fitting
MEP Stock supplies heavy-duty brass compression stop ends for terminating, capping, and pressure testing BS EN 1057 copper pipework. Conforming to BS EN 1254-2, each fitting features a robust solid blanking plug, precision compression nut, and high-purity olive for demountable, flame-free sealing up to 16 bar.
Durable Demountable Pipe Dead-Leg Capping & Pressure Testing
Capping off domestic copper supply lines during kitchen rip-outs, bathroom refurbishments, or system pressure testing is fast and flame-free with our brass compression stop ends. Unlike soldered or pressed end caps, compression stop ends are fully demountable and can be unscrewed when extending pipework.

Frequently Asked Questions: Brass Compression Stop End Pipe Fitting
Can this compression stop end be removed and reused?
Yes, compression stop ends are fully demountable, making them ideal for temporary caps. during bathroom refits or pressure testing. To reuse on a new pipe, simply fit a fresh olive.
Do I need to apply PTFE tape or jointing paste to the olive?
On clean, undamaged copper pipe, a dry olive will seal perfectly without paste. However, on older slightly scored copper pipe, plumbers often apply a light smear of non-hardening jointing compound (e.g. Fernox White) to the olive face.
Can this compression stop end be used on central heating pipework?
Yes, fully certified for heating circuits and domestic potable water up to 16 bar. and +110°C.
Can I use this stop end on plastic barrier pipe?
Yes, provided an approved manufacturer pipe stiffener/insert is placed inside the plastic pipe. before tightening the compression nut.
Is the olive and nut included in the fitting?
Yes, supplied complete with solid brass stop end body, compression nut, and olive.
How far should I tighten the compression nut?
Tighten hand-tight, then an additional 3/4 to 1 full turn with a spanner. Avoid extreme overtightening, which can crush the olive and distort the copper pipe.
