The 6B / 6B-LN Series BSP Male 60° Seat Bulkhead Fittings are designed for hydraulic systems requiring a secure connection through panels or equipment walls. The fitting features a BSP male thread with a precision-machined 60° cone seat, providing reliable metal-to-metal sealing when connected with matching BSP female fittings.
The bulkhead configuration enables installation through mounting plates, hydraulic tanks, manifolds, or machine housings, creating a stable and organized pipeline connection. The threaded body design ensures accurate positioning, while the optional lock nut version (6B-LN) improves fixing stability during installation.
Manufactured from premium carbon steel or stainless steel, the fitting provides excellent pressure resistance, mechanical strength, and long service life. Surface treatment enhances corrosion protection, making it suitable for demanding industrial environments.
The 6B series is widely used in hydraulic equipment, mobile machinery, industrial automation systems, fluid control systems, and general piping applications where reliable panel mounting connections are required.
