Parker 25KAIN13MPN Pneumatic Hose Coupler 1/4 in Brass

Product Description

The PARKER 25KAIN13MPN is a brass pneumatic hose coupler designed for compressed air and general-purpose pneumatic systems. It belongs to Parker's 25 Series high flow interchange line and accepts a 1/4-18 female NPSF threaded connection. The body diameter is 1/4 inch with an overall length of 2.19 inches and a hex size of 0.81 inches. Rated to 300 psi maximum working pressure, this coupler handles temperatures from -4 degrees F to 212 degrees F. Licensed HVAC technicians, plumbers, and industrial maintenance professionals install this type of fitting when connecting pneumatic hoses and tools to supply lines.

This coupler is suited for light industrial, commercial, and trade shop applications where high flow interchange compatibility is required. The threaded female NPSF connection makes it straightforward to install on standard pneumatic supply lines, compressor outlets, and tool drop stations. Its brass construction provides corrosion resistance in environments where moisture is present in the air supply. The 25 Series high flow interchange design allows faster air delivery compared to standard interchange couplers, making it a practical choice for impact tools, blow guns, and similar pneumatic equipment.
