Parker 14-1/2 F5OG-S Pipe Adapter Mstor X Nptf 5000 Psi

Product Description

The PARKER 14-1/2 F5OG-S is a male straight thread O-ring to female NPTF pipe adapter designed for high-pressure hydraulic and fluid power systems. It features a 1-3/16-12 male straight thread O-ring (MSTOR) inlet and a 1/2 inch female NPTF outlet, allowing technicians to transition between straight thread O-ring boss ports and tapered pipe thread fittings. Rated to 5,000 psi, the adapter is constructed from zinc plated steel for corrosion resistance in demanding industrial environments. Overall length is 1-1/16 inches and the hex size is 1-3/8 inches. It is installed by hydraulic and fluid power technicians in manufacturing, mobile equipment, and industrial process plumbing applications.

This adapter is suited for use in high-pressure hydraulic circuits, fluid power lines, and industrial piping systems where a straight thread O-ring boss port must be converted to a female NPTF connection. Typical installations include hydraulic manifolds, pump outlets, valve bodies, and cylinder ports in both stationary and mobile equipment. The NPTF female end provides a pressure-tight mechanical seal without sealant when properly torqued to a male NPTF fitting, though thread sealant is often applied as a precaution in high-vibration environments.

Key Features

• 5,000 psi pressure rating for high-pressure hydraulic service
• Male straight thread O-ring (1-3/16-12) inlet provides a leak-free boss port connection
• Female NPTF outlet delivers a pressure-tight pipe thread seal
• Zinc plated steel construction resists corrosion in industrial environments
• 1-3/8 inch hex size accommodates standard open-end or combination wrenches
• Compact 1-1/16 inch overall length minimizes space requirements in tight plumbing runs

Compatibility

Designed as an OEM-style adapter for hydraulic and fluid power systems requiring a male straight thread O-ring boss to female NPTF transition at 1/2 inch pipe size.

Installation Notes

Installation should be performed by a qualified hydraulic or fluid power technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. The O-ring on the male straight thread end must be inspected and properly seated before assembly; never reuse a damaged or deformed O-ring. Apply thread sealant to the NPTF threads per shop practice and tighten using a wrench on the hex flats only — do not grip the body of the fitting.
