Description
IMPORTANT: This is a NON-STANDARD 2" union O-ring measuring 2 5/8" center to center. This replacement seal fits specific heater and pump unions with 2 5/8" center to center groove dimensions. Please verify your union groove measures exactly 2 5/8" center to center before ordering, as the majority of standard 2" unions require the more common 2 1/2" center to center size. Designed for hot tub and spa applications requiring this precise 2 5/8" measurement specification.
Compatible with select 2" heater or pump unions that feature the larger 2 5/8" center to center O-ring channel. Measure carefully to ensure proper fitment.
