The EVER-TITE COUPLING PRODUCTS 310DSS is a Part D cam and groove coupling designed for quick-connect fluid transfer applications in industrial, agricultural, and trade plumbing systems. Constructed from stainless steel, this female coupler features a 1-inch FNPT threaded end and is rated for a maximum working pressure of 250 psi. The Part D configuration pairs a female coupler body with a female NPT thread, allowing direct connection to male-threaded pipe or hose fittings. Plumbers, pipefitters, and industrial service technicians install this style of coupling where fast disconnection and corrosion resistance are both required.
This coupling is suited for use in liquid transfer lines handling water, chemicals, fuels, and other compatible media where stainless steel construction provides adequate corrosion resistance. The 1-inch thread size fits standard 1-inch NPT male pipe ends. Typical install scenarios include tank truck loading and unloading, irrigation systems, chemical transfer manifolds, and general fluid handling lines in commercial and light industrial environments.
Designed as an OEM-style replacement or standard fitment for 1-inch Part D cam and groove coupling applications requiring female FNPT thread and stainless steel construction.
Installation is typically performed by plumbers or pipefitters working on fluid transfer systems. Depressurize and drain the line completely before removing or installing any cam and groove coupling. Verify thread engagement is full and secure before returning the line to service. Follow applicable IPC and facility safety guidelines for the media being transferred.
