Straight hose fitting with BSP female thread and flat-face O-ring seat — for high-vibration service requiring leak-free joints. straight, BSP parallel (G1/4 to G2), Flat-face with O-ring (ORFS-equivalent).
The BSP Female Flat Seat Hose Fitting is a straight hydraulic hose fitting in the BSP family — female-swivel thread with Flat-face with O-ring (ORFS-equivalent) sealing form. Compliant with ISO 228, ISO 12151-6, SAE J1453 (analogous flat-face).
Pressure rating matches the matching ferrule and host hose grade — see Indus Crimp Ferrules for compatibility tables. Tested to manufacturer-recommended impulse cycles when crimped to the correct ferrule diameter. Operating temperature -40°C to +120°C; refer to fluid compatibility chart for aggressive media.
Specify (a) the host hose grade and bore size, (b) the matching crimp ferrule (see the Crimp Ferrules category), and (c) the thread size you need. Indus crimps and pressure-tests the assembly before dispatch.
Pair with Indus crimp ferrules from the matching hose grade. For other thread families see the Metric, BSP, JIC 37°, DIN, and Japanese sub-categories under Hose Fittings.
