• Press Tool Required - Not Push Fit: This is an M Profile press fit fitting. You need a compatible press gun and M28 jaw to compress the sleeve and create a permanent seal on the pipe end. It cannot be hand-assembled.

• Permanently Seals a Pipe End - Single Press Connection: Push the open pipe end into the cap and press with your tool. The EPDM O-ring creates a permanent, water-tight termination. Use it to cap off any 28mm copper pipe you are not connecting.

• WRAS, DVGW and BSI Approved: Certified for hot and cold water services, vented and unvented heating systems, and chilled water. Rated to 16 bar from -24 deg.C to 110 deg.C. Compatible with BS EN 1057 R250 and R290 copper tube.

• EPDM O-Ring Seal - No Ongoing Maintenance: Once pressed, the cap is a permanent fitting. The EPDM sealing element is rated for decades in standard UK water and heating conditions.

• No Naked Flame - No Hot Works Permit: No solder, no flux, no open flame. Cap off live pipe ends in occupied buildings without hot works permits or fire protection measures.

• Deburr Before Pressing: Remove all burrs from the pipe end before inserting into the cap. A sharp burr is the most common cause of EPDM O-ring damage and a failed seal. Unpressed caps leak visibly at your pressure test. 25-year guarantee.

The LavaPlumb Copper Pressfit Stop End permanently seals the open end of a 28mm copper pipe. Push the pipe into the cap and press with a compatible M28 jaw and press gun. The EPDM O-ring creates a watertight, permanent termination - no solder, no flux, no naked flame. Where to use it: Capping off a supply point you are not connecting yet. Sealing a dead leg on a heating or water system. Terminating a pipe run during phased works. Important - deburr the pipe end first: A sharp burr left on the pipe after cutting is the most common cause of O-ring damage during press fit assembly. Deburr the pipe end with a deburring tool before inserting into the cap. The cap should slide on smoothly. Once pressed, the cap is permanent. Unpressed caps leak visibly at your pressure test before any pipework is concealed. WRAS Approved. DVGW Approved. BSI Approved. 16 bar from -24 deg.C to 110 deg.C. BS EN 1057 R250 and R290 compatible. 25-year manufacturer guarantee.
