The MACOMB GROUP APPROVED 830-003 is a Schedule 80 PVC threaded coupling designed for use in pressure piping systems where chemical resistance and durability are required. This molded gray coupling features female NPT (FNPT) connections on both ends and handles system temperatures up to 140 degrees F. Built to ASTM D1784 and ASTM D2467 Type 1 Grade I Cell Class 12454 standards, it is certified to NSF/LPCB requirements. Plumbers and pipefitters install this fitting in both new construction and repair applications where a reliable, all-threaded PVC coupling is specified.
This coupling is suited for residential and commercial plumbing, irrigation, and industrial fluid-handling systems that call for Schedule 80 PVC fittings. The 3/8 inch nominal size and FNPT connection type make it a standard choice for threaded assembly into Schedule 80 pipe runs. Its NSF/LPCB certification supports use in potable water and listed fire protection applications where code-compliant fittings are required.
Designed as an OEM-style replacement or new-installation fitting for 3/8 inch Schedule 80 PVC threaded piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Shut off system pressure and drain the line before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded PVC fittings, as this can crack the fitting body.
