Pasco Specialty Mfg Co 1320 Plastic Coupling Nut

Product Description

The PASCO SPECIALTY MFG CO 1320 is a plastic coupling nut used to join or secure threaded plumbing connections. Plastic coupling nuts are standard hardware in residential and light commercial plumbing assemblies, providing a lightweight, corrosion-resistant fastening point where metal hardware is unnecessary or undesirable. This type of fitting is commonly found in drain, waste, and vent assemblies as well as supply line connections. Licensed plumbers and experienced DIYers install this hardware as part of routine fixture connections and repairs.

The 1320 plastic coupling nut is suited for residential plumbing applications where a threaded coupling is needed to complete or secure a pipe or fitting connection. It is sold as a single unit, making it practical for targeted repairs or replacements without purchasing in bulk. Typical install scenarios include under-sink drain assemblies, lavatory supply connections, and similar light-duty threaded plumbing joints.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer familiar with threaded plumbing connections. Shut off the water supply to the affected line before beginning any work. Hand-tighten plastic coupling nuts carefully to avoid cross-threading or cracking the fitting from overtightening. Follow applicable local plumbing codes and IPC guidelines for fixture drain and supply connections.
