The TRENTON PIPE SS304-64003 is a 3/8-inch coupling fitting machined from 304 stainless steel. Couplings of this type join two sections of pipe or tubing of the same diameter in a straight-line configuration. The 304 stainless steel construction provides solid corrosion resistance in wet, chemical-exposed, or outdoor environments. This fitting is sold as a single unit and is a standard component stocked by plumbers, pipefitters, and mechanical contractors for maintenance and new-installation work across a wide range of piping systems.
This coupling is suited for residential and light commercial plumbing, process piping, and mechanical systems where stainless steel fittings are specified for corrosion resistance or hygiene requirements. The 3/8-inch size fits common small-diameter supply and distribution lines. It is a practical choice for repair, replacement, or new rough-in work where the pipe material and system pressure rating are compatible with 304 stainless steel fittings.
Designed as an OEM-style replacement or new-install fitting for 3/8-inch pipe systems requiring 304 stainless steel couplings.
Installation is typically performed by a licensed plumber or pipefitter. Shut off the water supply and depressurize the line before working on any fitting. Ensure thread engagement, sealant type, and joint method comply with applicable IPC or local plumbing code requirements. Verify that the pipe material, pressure rating, and fluid compatibility are appropriate for 304 stainless steel before installing.
