Parker 31382-12-12 Male Nptf Pipe Swivel Fitting

Product Description

The PARKER 31382-12-12 is a straight male NPTF pipe swivel fitting designed for hydraulic hose assemblies in fluid power systems. Machined from steel with a threaded NPTF connection, this fitting accepts hoses with a 0.75 inch (19.10 mm) inside diameter and a 3/4-14 thread size. At 3.7 inches in overall length and a 3/4 inch body diameter, it delivers a secure, leak-resistant swivel connection between hose and system port. Hydraulic technicians and fluid power mechanics install this fitting in mobile, industrial, and stationary hydraulic circuits where a rotating joint is needed to reduce hose stress and simplify routing.

This fitting belongs to Parker Series 82 and is engineered for use with Parker 801, 804, 821, 821FR, and 836 hydraulic hoses. It is suited for both industrial and mobile hydraulic applications where straight inline routing with NPTF port connections is required. The swivel design allows the hose to be positioned without twisting, making it particularly useful in tight plumbing layouts or equipment with limited clearance around the connection point.

Key Features

• Male NPTF threaded connection provides a dry-seal fit to minimize leakage at the port
• Swivel design reduces hose twist and torsional stress during installation and operation
• Steel construction for durability in high-pressure hydraulic service
• Straight body shape simplifies inline hose routing
• 3/4-14 NPTF thread size for compatibility with standard hydraulic ports
• Meets California Proposition 65 standards

Compatibility

Designed for use with Parker 801, 804, 821, 821FR, and 836 hydraulic hoses with a 12 mm hose size designation and 0.75 inch inside diameter.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and bleed the hydraulic system completely before removing or installing any fittings. Use appropriate thread sealant rated for hydraulic service on NPTF connections and verify thread engagement is correct before torquing. Inspect the hose end and fitting seat for damage before assembly to ensure a leak-free connection.
