The Flowflex compression air vent cap 15mm is a brass fitting used to release trapped air from copper plumbing systems. Its vent cap design helps reduce the risk of airlocks and maintain flow in water and heating installations.
Fitted using a compression method, it connects securely to 15mm pipework without the need for heat or specialist equipment. This product is commonly installed on new pipe runs or retrofitted to existing systems for easy manual venting during commissioning or routine maintenance.
