Parker 222P-6-MI22 Brass Iso Port Adapter Nptf M22x1.5

Product Description

The PARKER 222P-6-MI22 is a brass ISO port adapter designed to connect 3/8-18 NPTF male threads to M22x1.5 metric female ports. This fitting provides a reliable, leak-resistant transition between inch-standard and metric hydraulic or pneumatic circuits. Rated to 1,000 psi working pressure with a minimum working pressure of -53 psi, it handles the demands of pressurized fluid systems across a range of operating temperatures. Built from brass with a Viton seal material, the 222P-6-MI22 meets ISO 6149-3 and SAE 2244-3 standards. Licensed plumbers, hydraulic technicians, and fluid power specialists install this adapter as part of system assemblies requiring thread-form conversion.

This adapter suits residential and commercial applications wherever NPTF pipe threads must interface with ISO metric port connections. Typical scenarios include hydraulic manifold assemblies, pneumatic control systems, and equipment with metric-ported valve bodies mated to inch-standard supply lines. The 3/8-18 NPTF thread on one end and M22x1.5 metric thread on the other make it a direct solution for mixed-standard plumbing configurations encountered during system retrofits or OEM equipment servicing.

Key Features

• Brass construction for corrosion resistance in hydraulic and pneumatic service
• 1,000 psi maximum working pressure rating
• NPTF x M22x1.5 metric thread combination resolves inch-to-metric thread mismatches
• Viton seal material compatible with a broad range of hydraulic fluids
• Complies with ISO 6149-3 and SAE 2244-3 standards
• Operating temperature rated down to -65 degrees F

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and pneumatic systems requiring a 3/8-18 NPTF to M22x1.5 ISO port connection per ISO 6149-3 and SAE 2244-3.

Installation Notes

Installation is performed by licensed plumbers or certified fluid power technicians. Depressurize and isolate the hydraulic or pneumatic circuit fully before removing or installing any fittings. Apply thread sealant appropriate for NPTF connections only where required by the system design; do not over-apply sealant into the port bore. Verify torque requirements against the system manufacturer's documentation, as torque values are not specified in this product data.
