Flange Gasket for Taco Circulator Pumps

The Taco 007-007RP flange gasket seals the connection on compatible circulator pump models including 2KGV8, 2KGV9, 3GZV6, 4PC79, 5CHK4 and 5CHK6. It is designed for hydronic heating and plumbing installations that require a reliable Buna seal. Supplied as a pack of two, it provides a spare for maintenance or a second connection point.

Installation Fit and Clearance

The gasket has a 2.304 in inside diameter and a 1.984 in outside diameter with a 0.15 in thickness, matching the flange faces on the listed pump models. The Buna material conforms to irregular surfaces without requiring additional sealant. It frees the installer from improvising cut gaskets and ensures the bolt pattern aligns with the pump housing.

Sustained Temperature and Pressure Performance

Rated for a maximum working pressure of 125 PSI and a maximum temperature of 225 Degrees F, the gasket maintains its seal under continuous hot-water circulation. The Buna compound resists hardening and extrusion during long heating cycles. It is not suitable for systems that exceed these pressure or temperature limits or for applications requiring chemical compatibility beyond standard hydronic fluids.

Questions about this item

How much pressure can the 125 PSI flange gasket handle before it starts to leak?

The Buna gasket is rated for a maximum working pressure of 125 PSI and a maximum temperature of 225 Degrees F, so sustained use at or below those limits will maintain the seal.

Does the Buna material harden or degrade when the pump runs continuously at 225 Degrees F?

Buna is chosen for this flange gasket because it resists heat up to 225 Degrees F and pressure up to 125 PSI without hardening, keeping the seal stable during all-day operation.

Which pump models does the 2.304 in ID by 1.984 in OD gasket fit without extra parts?

It fits directly on pump numbers 2KGV8, 2KGV9, 3GZV6, 4PC79, 5CHK4 and 5CHK6, so no additional couplings or adapters are required.
