Compression Stop End Fittings

The Compression Stop End Fittings collection from PlumbHQ brings together a full range of heavy-duty, trade-trusted stop end fittings for sealing off open ends in water and gas pipework. Designed for plumbers, heating engineers, installers, and trade-savvy DIYers who need a reliable mechanical end to any copper or plastic pipe run, these fittings are engineered to meet the highest standards for strength, compliance, and straightforward installation without heat or soldering.

Compression Stop End Fittings: Direct Sealing Solutions

Stop ends are a crucial part of any professional pipe network. These fittings provide a robust mechanical cap at the end of a live or dead pipe branch, giving you a fast and secure way to safely terminate a system, perform upgrades, or maintain isolation for repairs. Within this collection, you’ll find compression stop ends in a variety of common UK sizes such as 8mm, 10mm, 12mm, 15mm, 22mm, 28mm, 35mm, 42mm, and 54mm. Pack options are available in multiples, so you can stock up for site work or pick the numbers for one-off repairs or system changes.

Key Features and Technical Details

Every stop end in this range comes with a compression nut and olive for a positive mechanical seal. Designed for hot and cold water, central heating circuits, and low-pressure gas applications, they are as suitable for fresh installs as they are for ongoing maintenance jobs. The mechanical joint means no flames, no flux, and no waiting – just cut the pipe, fit the olive, and tighten the nut for a permanent but demountable cap.

Compatible Materials, Trusted Brands, Full System Use

All fittings are made from high-grade brass for strength, corrosion-resistance, and long service life. Both classic brass and chrome finishes are available, allowing you to match exposed pipework neatly or keep everything aligned with your broader installation. These are WRAS Approved components, so you’re meeting UK water regulations every time. Manufactured to BS EN 1254-2 standards and compatible with BS EN 1057 copper pipe, each fitting lines up with professional expectations for reliability and system integrity. 

Flowflex, a respected name in the trade, supplies these stop ends for PlumbHQ. With a manufacturer-backed 25-year guarantee, you can fit every compression stop end with the knowledge it will stand up to routine use, system pressure, and real-world site demands.

Suitable Applications and System Performance

Compression stop ends are designed to work across a range of pressures and system types. Rated to PN16 (16 bar) and tested up to 110C operating temperature, they are right for almost every domestic and commercial project you might face. Use them to temporarily or permanently cap a pipe, set aside future branches, or maintain compliance during upgrades and repairs. Both copper and plastic pipes (with the correct inserts) are supported.
