Seal
PU for brass threaded hose fittings
PTFE for stainless steel hose fittings
Operation
Screw hose couplings are used to connect hoses with male or female BSP, BSPT or NPT threads. The hose fitting can be divided into 3 types:
1. Screw hose couplings with smooth surface – used when connecting with an aluminum double-jaw clamp
2. Screw hose couplings with serrated hose shank – used for worm drive clamp assemblies.
3. Screw hose couplings with serrated hose shank and collar – used for installation with worm drive clamps
The parallel BSP thread seal used as standard on threaded hose fittings complies with EN ISO 228-1. The leak-proof connection is achieved by using a flat seal. The hose fittings are easy to assemble by hand or with a wrench.
N.B.: Screw hose couplings are not interchangeable with steam hose fittings due to differences in application and overall dimensions.
