The 1BJ BSP Male Double Use for 60° Cone Seat or Bonded Seal / JIC Male 74° Cone is a versatile hydraulic adapter designed to provide secure, leak-free connections in both BSPP and SAE JIC hydraulic systems. Featuring a BSP male thread, this fitting offers dual sealing capability, allowing connection by either a 60° cone seat or bonded seal (Dowty washer) on the BSP side, while the opposite end utilizes a 74° JIC male cone for reliable metal-to-metal sealing.
Manufactured from high-quality carbon steel or stainless steel and produced with precision machining, this hydraulic fitting provides excellent pressure resistance, corrosion protection, and long service life under demanding operating conditions. Depending on the material and size, the maximum working pressure can reach 620 bar (9000 PSI).
Available in a complete range of BSP thread sizes from 1/8" to 4", the 1BJ hydraulic fitting is widely used in construction machinery, agricultural equipment, industrial hydraulic systems, mining equipment, and other high-pressure fluid power applications. It complies with international hydraulic fitting standards, ensuring excellent interchangeability and dependable sealing performance.
