Plumbeeze UNA-12 Nylon Insert Adapter 1-1/4 in

Product Description

The PLUMBEEZE UNA-12 is a 1-1/4 inch nylon insert adapter designed to connect female pipe threads to poly pipe in a straight-line configuration. Built from nylon, this fitting handles cold water service in both above-ground and underground installations. Nylon construction offers greater toughness and impact resistance than standard poly insert fittings, making it a reliable choice for water service and agricultural distribution lines. Licensed plumbers and irrigation professionals specify this fitting where a durable, NSF-approved connection to poly pipe is required. Stainless steel hose clamps are recommended to secure the fitting to the pipe.

This adapter is suited for residential and agricultural water service applications where poly pipe transitions to threaded fittings are needed. It performs in both above-ground and direct-burial scenarios, making it a common choice for irrigation systems, rural water lines, and service entry connections. The fitting is rated for cold water use only and is not intended for hot water, steam, or high-temperature fluid service.

Installation Notes

Installation is typically performed by a licensed plumber or irrigation technician. Before making any connections, shut off the water supply and depressurize the line. Use stainless steel hose clamps to secure the nylon insert fitting to the poly pipe — do not use standard galvanized clamps in corrosive or direct-burial environments. This fitting is rated for cold water only; do not use on hot water, steam, or pressure systems exceeding the fitting material rating.
