BULKHEAD FITTINGS INCH BSP
Bulkhead fittings ( long ) with British Standard Pipe (BSP) inch threads
Bulkhead connectors are connectors with two male threads, where one side is longer and is intended for screwing on a locknut. Bulkhead connectors are used , if you need to fix something through a sheet , wall or other element. Fittings of this type have a cone on both sides, thanks to which they can be used for connecting hydraulic hoses. Connectors of this type occur both with two identical threads as well as in a reduction version ( inch thread / metric thread ).
- execution : zinc-plated free-cutting steel
- threads : British Standard Pipe ( BSP ) , inch-metric and others
- standard threads : 1/4", 3/8", 1/2", 5/8", 3/4", 1", 11/4", 11/2", 2"
BSP inch bulkhead fittings leak-proof passages through walls and bulkheads
BSP (British Standard Pipe) inch bulkhead fittings are durable fasteners used in power hydraulic systems for leak-free routing of pressure lines through housing walls, machine frames, bulkheads and tanks. They are characterized by an elongated body with an external thread along the entire length of the mounting part and a dedicated bulkhead locknut, which allows for secure and rigid tightening of the element on the panel. The use of the British BSP inch standard with a 60° sealing cone (AGR/DKR) ensures the highest tightness and resistance to vibrations, pressure surges and difficult operating conditions. These fittings are widely used in agricultural, construction, industrial machinery as well as in municipal and specialized vehicles.
Application and technical characteristics of BSP bulkhead fittings
Bulkhead elements with BSP inch thread were designed for permanent protection of hydraulic lines at points of passage through partition walls. They allow for the connection of flexible hoses or rigid pipes on both sides of the bulkhead, preventing their damage due to friction against the edges of the hole.
- 60° conical seal: The connection is sealed on a universal 60° cone metal-to-metal contact or by using a sealing washer, which eliminates working oil leaks.
- BSP (G) inch thread standard: Available in a full size range from G 1/8" to G 2", fully compatible with universal European fittings.
- Secure panel mounting: The set includes a massive bulkhead locknut, which stabilizes the position of the fitting in the mounting hole and prevents it from rotating under load.
- High pressure strength: Forged free-cutting steel protected by zinc plating withstands operating pressures ranging from 160 bar for large diameters to 350-400 bar for smaller dimensions.
- Corrosion resistance: Passivated zinc coating protects the body against moisture, road salt and cleaning chemicals.
Why is it worth choosing BSP inch bulkhead fittings at the HYDRON store?
BSP bulkhead fittings available in the HYDRON offer are produced in compliance with rigorous quality standards ISO 8434-6 and BS 5200. Precise execution of the thread profile and accurate processing of the conical surfaces prevent leaks in the system during continuous operation under pressure. The use of bulkhead connectors significantly simplifies the service and disassembly of individual machine modules without the need to dismantle the entire oil line. For the construction and maintenance of a complete pressure system, we encourage you to select additional products from our range, such as flexible hydraulic hoses, matching hose ends, self-sealing test points and precise measuring kits.

Frequently Asked Questions (FAQ)
What is a BSP inch bulkhead fitting used for?
A BSP bulkhead fitting is used for stable passage of a hydraulic hose through a wall, housing or bulkhead of a machine. The elongated threaded part allows for tightening the fitting on the panel using a locknut.
What is included in the BSP bulkhead fitting kit?
A standard kit includes a bulkhead fitting body with two BSP male connections and a strong steel bulkhead locknut used to secure the fitting in the mounting hole.
What is the difference between BSP parallel thread (BSPP) and BSPT tapered thread?
BSP (BSPP) thread is a parallel thread with a 60° sealing cone on the face, while BSPT is a tapered thread that seals directly on the thread profile using a sealant.
What pressure do bulkhead fittings with BSP threads withstand?
Operating pressure depends on the thread size: for smaller cross-sections (1/8" - 1/2") it is usually 315-350 bar, while for large diameters (1.1/4" - 2") it is in the range of 160-200 bar.
