Rehau 316252-002 Flow Gauge Replacement Kit 1 Inch

Product Description

The REHAU 316252-002 is a flow gauge replacement kit designed for use on the supply side of PRO-BALANCE manifold systems. The kit allows field technicians to replace worn or damaged flow gauges without swapping out the full manifold assembly. Each gauge connects via a 3/8 inch threaded connection and includes an integrated shut-off valve that is manually activated using a standard vent key. The nickel-plated finish provides corrosion resistance in hydronic system environments. This kit is sized for 1 inch nominal manifold applications and is installed by licensed plumbers and radiant heating technicians.

This replacement kit is intended for use on PRO-BALANCE manifold supply-side installations in residential and light commercial radiant heating systems. It is specifically engineered to restore accurate flow measurement and individual loop shut-off capability after gauge failure or system servicing. The 3/8 inch threaded connection and integrated valve design allow for direct replacement without modifying the existing manifold body.

Key Features

• Direct replacement for supply-side flow gauges on PRO-BALANCE manifolds
• Integrated shut-off valve activated with a common vent key
• 3/8 inch threaded connection for straightforward field installation
• Nickel-plated finish for corrosion resistance in hydronic environments
• 1 inch nominal size matches standard PRO-BALANCE manifold sizing

Compatibility

Designed as a direct replacement for flow gauges on the supply side of REHAU PRO-BALANCE manifold systems with a 3/8 inch threaded gauge port.

Installation Notes

Installation should be performed by a licensed plumber or qualified radiant heating technician. Before removing the existing flow gauge, shut off flow to the affected manifold loop and relieve system pressure. Liquid medium-strength thread sealant must be applied to the threaded connection during reinstallation — do not use tape-style sealants. Hand-tighten first, then snug with appropriate wrenches, taking care not to over-torque the manifold body.
