Designed for quick, tool-free connection and disconnection, the Aeroquip Coupling-ST Series FEMale-Brass is a 1/8" port, female-half socket built to Hansen ST Series standards. Brass construction paired with Buna-N seals makes it well suited for fluid transfer across a broad range of industries, including chemical processing, food and beverage, marine, medical, injection molding, pressure washing, and steam cleaning.
The coupling uses a push-to-connect interface on the female end and a 1/8" NPTF port on the male end, with an internal ball lock mechanism providing secure engagement. A straight-thru valve design supports a flow rate of 2.7 gallons per minute, and the fitting is rated for use down to -40°F minimum working temperature. It exceeds ISO 16028 operating pressure requirements and requires no special tools for connection or disconnection.
