Parker 222P-6-MI16 Brass Iso Port Adapter Nptf X M16

Product Description

The PARKER 222P-6-MI16 is a brass ISO port adapter designed to connect NPTF pipe threads to metric M16x1.5 ports in hydraulic and fluid power systems. It provides a 3/8-18 NPTF male thread on one end and an M16x1.5 metric thread on the other, allowing technicians to bridge inch-standard plumbing with ISO metric ported components. The adapter is rated to 1,000 psi working pressure and carries a Viton seal, making it suitable for use across a broad temperature range. It meets ISO 6149-3 and SAE 2244-3 standards, confirming dimensional and performance compliance for professional hydraulic installations.

This adapter is used in hydraulic systems, fluid power circuits, and industrial plumbing where NPTF-threaded lines must interface with ISO metric ports on valves, manifolds, cylinders, pumps, or other components. Typical installation environments include mobile equipment, industrial machinery, and stationary hydraulic power units. The compact brass construction makes it a practical solution for tight-space plumbing transitions in both shop and field service settings. It is installed by hydraulic technicians, pipefitters, and mechanical maintenance professionals.

Key Features

• Viton seal material for broad fluid and temperature compatibility
• Meets ISO 6149-3 and SAE 2244-3 standards
• Rated for minimum working temperature of -65 degrees F

Compatibility

Designed for use with hydraulic and fluid power components featuring ISO 6149-3 metric M16x1.5 ports, mated to NPTF 3/8-18 inch-standard pipe connections, in accordance with SAE 2244-3.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and bleed the hydraulic circuit completely before removing or installing any fittings. Apply thread sealant appropriate for the system fluid and compatible with Viton seals; do not use PTFE tape on NPTF threads where it may interfere with thread engagement. Verify port thread size and standard before installation to avoid cross-threading or seal damage.
