Uponor q2121000 Manifold Inlet 1 Inch F1960

Product Description

The UPONOR q2121000 is a 1-inch F1960 expansion fitting designed as an inlet connection for radiant and hydronic manifold systems. This fitting integrates with PEX-a tubing using the ProPEX expansion method, creating a reliable, leak-resistant joint without solder or crimp rings. It is installed by licensed plumbers and radiant heating technicians working on residential and light commercial hydronic distribution systems. The F1960 connection standard requires an expansion tool to flare the PEX-a tubing before the fitting is seated, producing a strong mechanical bond as the tubing memory contracts around the fitting body.

This manifold inlet is used where a supply or return branch must be connected to a distribution manifold in a radiant floor heating, snowmelt, or domestic hot water recirculation system. The 1-inch size is a common trunk-line dimension on residential and light commercial manifold assemblies. It is suited for new construction and retrofit installations where UPONOR PEX-a manifold components are already specified or in use.

Compatibility

Designed as an OEM-style inlet fitting for UPONOR F1960 PEX-a manifold systems using 1-inch connections. No additional compatible model numbers were specified in the product data.

Installation Notes

Installation should be performed by a licensed plumber or qualified radiant heating technician familiar with the F1960 ProPEX expansion process. Shut off system water supply and depressurize the line before removing or installing any manifold components. An UPONOR-compatible PEX-a expansion tool sized for 1-inch tubing is required to properly flare the pipe end before seating the fitting. Follow applicable plumbing codes including IPC and local jurisdiction requirements for hydronic system connections.
