Hose Fittings Adapters

Hydraulic fitting adapters are different hydraulic components (pumps, pipelines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and some auxiliary components, such as level gauges, thermometers, pressure gauges, and so on) connected to form a closed circuit of the hydraulic system is to play a role in connecting an accessory. Hydraulic fittings can withstand the high strength of the pressure, if the hydraulic oil fittings have sand holes, small holes or the pressure is too high to withstand such a large pressure and the impact of the burst is quite large. Hydraulic fitting adapters are widely used in the military, energy, petrochemical, electric power, ships, automobiles, rail transport, construction machinery, mining, metallurgy, steel mills, marine engineering and other industries in the hydraulic piping system.

Types of Hose Fittings Adapters

BSP MALE 60°SEAT(BONDED SEAL)

The BSP Male 60° Seat with Bonded Seal ensures a highly secure, leak-resistant hydraulic connection. Its BSP thread and 60° conical seat, enhanced by the bonded seal, provide reliable sealing under high pressure for demanding industrial and mobile equipment applications.

STRAIGHT UNION

A straight union (or coupling) is a fundamental pipe fitting used to connect two pipes in a straight line. It typically has two female threaded ends for creating secure, leak-free joints in plumbing and industrial fluid systems.

ELBOW UNION

An elbow union is a pipe fitting that connects two pipes at a 90° or 45° angle, enabling directional changes in fluid systems. Available in materials like stainless steel, it ensures durable and reliable performance across industrial and plumbing applications.

UNION TEE

A Union Tee is a T-shaped pipe fitting that connects three pipes of equal diameter at a single point. It allows for fluid or gas branching and combination, offering flexibility and ease of installation for efficient distribution in piping systems.

BULKHEAD UNION

A bulkhead union is a specialized pipe fitting designed to create a secure, leak-proof connection between two pipes through a wall or barrier. It ensures fluid continuity and structural integrity, reliably managing pressure and temperature variations in industrial and plumbing systems.

BULKHEAD UNION ELBOW

A bulkhead union elbow is a 90-degree pipe fitting designed to pass through a wall or panel. It enables a secure, leak-proof directional change in fluid lines while maintaining a sealed connection across the barrier in industrial and plumbing systems.
