Parker 25SFIN17SXZ High Flow Plug Coupling 3/8 Fnpt Steel

Product Description

The PARKER 25SFIN17SXZ is a high flow pneumatic plug coupling designed for compressed air and pneumatic tool applications. Built from steel, this threaded plug features a 3/8 inch FNPT connection and a 15/16 inch body diameter, making it compatible with high flow interchange systems. It carries a maximum working pressure of 300 psi and is rated for temperatures from -4 degrees F to 212 degrees F. Licensed HVAC technicians, industrial maintenance mechanics, and pneumatic system installers use this fitting to connect air lines quickly and reliably in demanding shop and field environments.

This plug coupling suits residential and commercial pneumatic installations where high flow capacity is required. It threads directly into female NPT ports on air tools, compressors, manifolds, and pneumatic control equipment. The steel construction holds up in high-cycle environments where repeated connect and disconnect operations are routine. Its hex body allows for wrench tightening to ensure a leak-free threaded seal.

Key Features

• High flow plug design supports higher air volume than standard interchange couplings
• 3/8 inch FNPT threaded connection for direct installation into female NPT ports
• Steel construction for durability in industrial and shop environments
• 300 psi maximum working pressure suits most compressed air systems
• Wide temperature range of -4 degrees F to 212 degrees F
• 0.81 inch hex size allows standard wrench installation

Compatibility

Designed as an OEM-style high flow interchange plug coupling for pneumatic systems using 3/8 inch FNPT threaded connections and high flow interchange couplers.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic systems and compressed air plumbing. Depressurize and lock out the air supply before removing or installing any coupling. Apply thread sealant tape to the FNPT threads per system requirements to ensure a leak-free connection. Tighten using an appropriately sized wrench on the hex body — do not over-tighten, as this may damage the threads.
