Gasket and sealing ring set compatible with Taco 007 and Taco circulator pump systems, suitable for taco pump gasket replacement, taco pump seal service, and taco valve o ring connections in closed loop water circulation, hydronic heating, boiler feed, and household hot water return lines.
Temperature and pressure resistant rubber material helps support stable sealing at pump connection points, reducing liquid seepage and maintaining balanced circulation in taco water pump systems. This gasket kit supports routine maintenance, damaged seal replacement, and long term pump connection stability in residential and light commercial hydronic circulation lines.
Each gasket is structured to fit standard Taco 007 pump connection points, offering direct installation compatibility for water circulation pump service, system inspection replacements, and sealing ring upgrades.

【Compatibility】 Replacement flange gaskets compatible with Taco 007-007RP gasket set, used on many in-line circulator pumps compatible with Taco Series 005, 006, 007, 008, 009, 00R, 0010, 0011, 0012, 0013, 0014 and 0015 in closed-loop hydronic hot water systems. Covers the model codes published for the 007-007RP gasket set, with typical examples such as 003-ZF4, 005-F2, 006-F4, 007-F5, 008-F6, 009-F5, 0010-F3, 0011-F4, 0013-F3 and 0014-F1. Match your pump series and code with the model list in the product description before ordering.
【Replacement Part Numbers】Replaces 007-007RP rubber flange gasket set compatible with Taco in-line circulators and cross references catalog number 110-339RP used on a wide range of Series 005, 006, 007, 008, 009, 00R and 0010–0015 pumps. If your existing flat flange gasket is marked as 007-007RP / 110-339RP or matches this two-bolt circulator pump flange pattern, this replacement set is designed to follow that style.
【Nitrile Rubber vs Other Materials】Made from nitrile rubber (NBR), a durable elastomer commonly used in hot water and glycol-based systems. Compared with fiber or paper gaskets, nitrile stays more flexible and compressible, helping it conform to minor flange irregularities and maintain a tighter seal over time. Compared with general-purpose rubber, NBR offers better resistance to hot water, system treatment chemicals and light oil residue around the pump, supporting stable sealing under typical hydronic operating temperatures.
【Application Scenarios】 Intended for hydronic hot water circulation loops using in-line circulator pumps compatible with Taco, including boiler room primary and secondary loops, baseboard heating circuits, radiant floor heating manifolds, fan coil units and domestic hot water recirculation lines. Suitable for residential and light-commercial HVAC maintenance, planned circulator replacement and sealing repairs at flanged pump connections during seasonal tune-ups or emergency leak service.
【6 Pack for Service Work】Includes 6 nitrile rubber flange gaskets, a practical quantity for common hydronic service tasks. Use 2 gaskets for one circulator pump flange connection, then keep the remaining pieces for a second pump, a follow up visit, or as service spares. Helpful for contractors and maintenance teams working on multiple circulators in the same boiler room, seasonal tune ups, or leak calls. Keeping extra gaskets on hand reduces repeat ordering and helps you finish repairs without pausing a job to source small parts.
