Plumbeeze UNC-12 Nylon Insert Coupling 1-1/4 in

Product Description

The PLUMBEEZE UNC-12 is a 1-1/4 inch nylon insert coupling designed to join two sections of polyethylene pipe in a straight-line connection. Built from nylon rather than standard poly insert material, this fitting delivers greater toughness and better impact and shock resistance — an important advantage in field conditions where fittings take abuse during installation. It is rated for cold water service only and sold in a package of 10 units. Installation requires stainless steel hose clamps to secure the fitting to the pipe on both ends. This coupling is NSF approved for potable water contact, making it suitable for residential and agricultural water service lines.

The UNC-12 is used in both above-ground and underground installations for water service and agricultural irrigation systems. It is the correct choice when extending or repairing polyethylene supply lines in residential well systems, rural water distribution, and farm irrigation layouts. The cold-water-only rating must be observed — this fitting is not intended for hot water or pressure heating applications. Its nylon construction gives it an edge over standard poly insert fittings in applications where ground movement, vibration, or rough handling is expected.

Key Features

• Nylon construction absorbs shock and impact better than standard poly insert fittings
• NSF approved for potable cold water applications
• Suitable for both underground and above-ground installation
• Straight-line coupling joins two pieces of polyethylene pipe end to end
• Requires stainless steel hose clamps for a secure connection to pipe
• Sold as a package of 10 couplings

Compatibility

Designed for use with 1-1/4 inch polyethylene pipe in cold water service and agricultural applications. Compatible with above-ground and underground poly pipe installations where nylon insert fittings are specified.

Installation Notes

Nylon insert couplings are installed by plumbers and irrigation contractors working with polyethylene pipe systems. Shut off the water supply and relieve line pressure before cutting or fitting pipe. Insert the coupling fully into each pipe end and secure with stainless steel hose clamps — do not substitute other clamp types. This fitting is rated for cold water only; do not use on hot water lines, steam, or any heated fluid service.
