JBL Double Stopcock + Quick Coupling 16/22

The JBL Double Stopcock + Quick Coupling 16/22 is a quick-release coupling with two taps for disconnecting external filters from their hoses. Both stopcocks seal the hose ends, so filter maintenance is quick and drip-free. It fits 16/22mm hoses.

Key features of the JBL Double Stopcock

• Two stopcocks seal both hose ends
• Quick release
• Easier filter maintenance
• Fits 16/22mm hoses

Matching your hose size

The two numbers give the hose’s inside and outside diameter in millimetres: the 12/16 version suits hoses of 12mm inside and 16mm outside, and the 16/22 version suits 16mm inside and 22mm outside. Check your filter hose or manual before ordering; JBL’s own CristalProfi external filters use one size or the other depending on the model. Each pack holds one coupling, so an external filter usually needs two, one on the intake hose and one on the return. JBL fits ball valves and locking nuts at both ends, and the coupling stays rotatable once assembled, which helps prevent kinks in the hose.

Good to know

Close both taps before separating the coupling, and check the seals occasionally for wear.
