Parker PT-00418 Pipe Adapter M12x1.5 Orr X Nptf 5000 Psi

Product Description

The PARKER PT-00418 is a straight industrial pipe adapter designed for high-pressure hydraulic and fluid-power systems. It connects an M12 x 1.5 female thread on the ORR (O-Ring Retained) side to a NPTF (National Pipe Taper Fuel) male thread, providing a leak-resistant transition between metric and standard tapered pipe connections. Rated to a maximum working pressure of 5,000 psi, this adapter is built for demanding industrial and mobile hydraulic applications. Licensed plumbers, pipefitters, and hydraulic system technicians typically install this fitting during system assembly or repair where metric-to-NPT conversion is required.

This adapter is suited for use in hydraulic circuits, fluid transfer lines, and instrumentation plumbing where an M12 x 1.5 metric port must interface with a NPTF threaded component. The straight fitting geometry keeps plumbing runs compact and inline. Typical install scenarios include machine tool hydraulics, mobile equipment, and industrial manifold assemblies. The ORR connection style provides positive sealing via an O-ring retained at the port face, reducing the risk of thread-initiated leaks in high-cycle systems.

Key Features

• Maximum working pressure rated to 5,000 psi for high-pressure hydraulic service
• M12 x 1.5 female thread on the ORR side for metric port compatibility
• NPTF male thread provides a pressure-tight taper-thread seal without additional sealant in many applications
• Straight fitting shape for compact, inline plumbing runs
• ORR connection type delivers O-ring face sealing for reliable leak-free performance
• Sold in a package quantity of 5 units per order

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid-power systems requiring an M12 x 1.5 ORR to NPTF straight adapter rated to 5,000 psi. No specific equipment model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber following applicable industry standards. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Inspect threads and sealing surfaces for damage before assembly. Apply thread sealant or tape only on the NPTF side if required by the system design; the ORR side relies on the O-ring for sealing and does not require additional sealant.
