This silicone hose set connects a U-tube manometer to the test nipples of gas systems, for measuring pressure when commissioning or diagnosing faults in heating systems. It includes two hoses — one 4mm and one 6mm in diameter, both 50cm long — to cover the range of test nipple sizes fitted to domestic and commercial heating appliances.
Being silicone, the hoses remain flexible even in low temperatures and resist excessive wear from repeated connections and disconnections at test points. The maximum pressure rating is 700hPa, suited to testing domestic and small commercial gas installations. A push-fit adapter nose-piece allows tool-free hose fitting.

Ideal For
Gas pressure measurement on domestic and commercial heating systems using a U-tube manometer.
Boiler commissioning and fault diagnosis requiring pressure testing at test nipples.
Why Buy This Product?
Having both 4mm and 6mm hoses in one set covers the different test nipple sizes found across domestic and commercial heating appliances, so the right connection is on hand without needing to guess in advance which size a job will require. Silicone construction holds up to repeated connect/disconnect cycles at test points better than more rigid tubing, and the push-fit nozzle keeps setup quick without needing separate tools.
