HCP SERIES
Connect under pressure flat face male couplings made to the ISO 16028 Standard
Holmbury’s HCP Series male couplings are designed to connect under pressure by hand with up to 350 bar (5075 psi) locked in the male half, making it an ideal choice for applications where the ability to connect under pressure is essential. The HCP Series also benefits from all the key features of the HQ Series flat face couplings.
FEATURES
- Designed to connect with the HQ Series
- Flat faces are easily wiped clean
- Allows for minimal inclusion of air and contaminants during connection
- Flat face design prevents fluid loss during disconnection
- Bidirectional flow
- Connect under pressure with up to 350 bar (5075 psi) locked in the male half
- Female half of HQ Series must have zero pressure when connecting male HCP under pressure
CONSTRUCTION
- Carbon steel with zinc nickel plating (1200 hours with no red rust in salt spray tests)
- Fitted with Nitrile seals
ACCESSORIES
- Dust Caps are available for the HCP Series
APPLICATIONS
- Hot environments where thermal expansion of trapped oil may take place
- High pressure pulse applications
- Leak free environments
- Construction plant
- Mobile equipment
- General industrial
- Agricultural
- Skid steer loaders
