Parker 25KAAN13MPN Pneumatic Coupling 1/4-18 Npt Brass

Product Description

The PARKER 25KAAN13MPN is a brass pneumatic hose coupler designed for high-flow compressed air and pneumatic tool applications. Part of Parker's 25 Series, it features a 1/4-18 NPT male threaded connection and a 1/4 inch body diameter. The coupler is rated for a maximum working pressure of 300 psi and operates across a temperature range of -4 degrees F to 212 degrees F. Its brass construction provides corrosion resistance and durability in demanding shop and field environments. Licensed HVAC technicians, plumbers, and general contractors commonly use 25 Series couplers when building or servicing pneumatic tool lines and air distribution systems.

This coupler is suited for residential and commercial pneumatic service lines where a high-flow interchange fitting is required. The 1/4-18 MNPT thread makes it compatible with standard NPT-threaded air lines, compressor outlets, and pneumatic tool inlets. The high-flow interchange design allows for efficient air transfer with reduced pressure drop, making it appropriate for impact wrenches, air ratchets, blow guns, and similar tools. Its compact overall length of 2.34 inches and 0.81 inch hex size allow for easy installation and removal in tight spaces.

Key Features

• High-flow interchange design reduces pressure drop across the connection
• Brass construction resists corrosion in compressed air and light fluid service
• 1/4-18 MNPT thread conforms to NPT standard for broad system compatibility
• Rated to 300 psi maximum working pressure for demanding pneumatic applications
• Temperature range of -4 degrees F to 212 degrees F suits most shop and field conditions
• 0.81 inch hex size allows standard wrench installation and removal

Compatibility

Designed as an OEM-style replacement or service fitting for pneumatic systems using 25 Series high-flow interchange couplers with 1/4-18 NPT threaded connections.

Installation Notes

Installation is typically performed by a qualified pneumatic or mechanical technician. Depressurize the air line completely before removing or installing any coupler. Apply thread sealant tape or compound rated for compressed air service to the NPT threads before assembly. Use an appropriately sized wrench on the 0.81 inch hex to tighten to a secure fit without over-torquing the brass body.
