Parker 11356-4-4 Male Pipe Swivel Straight Fitting 3000 Psi

Product Description

The PARKER 11356-4-4 is a male pipe swivel straight fitting designed for hydraulic hose assemblies operating at pressures up to 3,000 psi. Constructed from steel, this fitting connects a 1/4-inch hose to a 1/4-18 male pipe thread with a swivel design that allows rotational adjustment during assembly without twisting the hose. The 5/8-inch hex size accommodates standard wrenching during installation. At 0.148 pounds, this compact fitting is suited for high-pressure hydraulic circuits in industrial, mobile, and fluid-power applications where a leak-free, straight-line connection is required.

This fitting is used in hydraulic hose assemblies where a straight-thread-to-pipe-thread transition is needed at the hose end. The swivel feature is especially useful in tight installations where hose routing makes it difficult to achieve proper alignment without applying torsional stress to the hose. It is installed by hydraulic system technicians and fluid-power specialists working on equipment requiring reliable 3,000 psi rated connections at 1/4-inch hose ports.

Key Features

• 3,000 psi pressure rating suitable for high-pressure hydraulic circuits
• Steel construction for durability in demanding fluid-power environments
• Swivel body allows hose alignment without twisting during installation
• 1/4-18 male pipe thread for standard NPT port connections
• 5/8-inch hex provides a wrench flat for controlled tightening
• Straight configuration for direct inline hose-to-port connections

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies requiring a 1/4-inch hose ID with a 1/4-18 male pipe swivel straight end connection rated to 3,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and lock out the hydraulic system completely before removing or installing any fittings. Use the hex flats and a properly sized wrench to tighten to the fitting manufacturer's recommended procedure — do not over-tighten, as this can damage threads or the sealing surface. Inspect threads and sealing surfaces for damage before assembly and verify pressure rating compatibility with the full system before returning to service.
