Parker 1GU56-4-4 Jis Bsp 60 Cone Flare Female Swivel Fitting

Product Description

The PARKER 1GU56-4-4 is a JIS BSP 60-degree cone flare female swivel hydraulic hose fitting manufactured from steel. It is designed to create leak-resistant, swiveling connections in hydraulic hose assemblies operating at up to 5,000 psi. The female swivel design allows the fitting body to rotate during assembly, reducing hose twist and simplifying installation in tight or awkward routing situations. The 60-degree cone flare seating geometry is common in JIS-standard hydraulic systems. This fitting is sized for a 4 mm hose with a 1/4-19 BSPP thread connection and is installed by licensed hydraulic technicians and industrial maintenance professionals.

This fitting is suited for hydraulic hose assemblies in industrial, mobile, and fluid-power applications that follow JIS or BSP standards. The BSPP (British Standard Parallel Pipe) thread form is widely used in equipment manufactured to European and Asian specifications. At 5,000 psi rated working pressure, it is appropriate for medium- to high-pressure hydraulic circuits. The swivel feature is particularly useful in applications where the hose must remain stationary after assembly or where routing geometry makes fixed-end fittings difficult to tighten without inducing twist.

Key Features

• JIS BSP 60-degree cone flare female swivel design for secure, leak-resistant seating
• 5,000 psi working pressure rating for medium- to high-pressure hydraulic service
• BSPP 1/4-19 thread for compatibility with BSP-standard ports and adapters
• Swivel body reduces hose twist during assembly and simplifies routing
• Steel construction for durability in hydraulic fluid environments
• Sized for 4 mm hose with a 1/4-inch hose diameter

Compatibility

Designed for use with 4 mm hydraulic hose assemblies requiring a JIS BSP 60-degree cone flare female swivel end connection with a 1/4-19 BSPP thread. Suitable for equipment with BSP-standard hydraulic ports operating within the 5,000 psi pressure rating of this fitting.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before disconnecting or assembling any fittings. Inspect the cone flare seating surface and mating port for damage or contamination before assembly. Do not overtighten swivel fittings, as excess torque can deform the cone sealing surface and cause leakage.
