Key Features & Benefits – 4 mm vacuum hose check valve
The 4 mm vacuum hose check valve (vacuum check valve) is an inline valve designed to support one-way flow and help prevent liquid and gas backflow. It is intended for 4 mm vacuum hose connections.
The transparent design helps with quick inspection after installation. The connector is made from PVED plastic, and the valve can be used in vacuum systems such as brake booster circuits and other pneumatic applications.
When is this useful?
It is useful when a vacuum or pneumatic branch needs stable directional behaviour and you want to reduce the chance of reverse flow affecting system operation.
