The CMP 26200-210-632 Hi-Temp Union T-Gasket is engineered for high-temperature pool and spa plumbing applications, particularly designed to seal Custom Molded Products (CMP) Hi-Temp union assemblies (notably 1½″ x 2″ size unions). This T-shaped gasket—with one flat side and one “T” side—ensures a reliable, leak-free connection in hot-water or high-flow environments where standard gaskets may fail. Its durable elastomeric material resists deformation, chemical exposure, and thermal stress, making it ideal for both residential and commercial pool systems that experience elevated temperatures around heaters, heat exchangers or solar-augmented loops.

Additional Info
This section answers the in-store questions customers commonly ask about the CMP 26200-210-632 Hi-Temp Union T-Gasket. It explains how to confirm compatibility, where this gasket is used, and how to prepare for fast in-store pickup at Discount Pool Mart.
Compatibility, Union Fit & Heater System Use
The 26200-210-632 gasket is designed specifically for CMP Hi-Temp union assemblies used around heaters, heat pumps, and solar-heated plumbing. These answers help you confirm it fits your system before coming to the store.
How can I confirm this T-gasket fits my CMP Hi-Temp 1.5″ x 2″ union?
Check the union tailpiece for CMP markings and a stepped 1.5″ x 2″ sizing profile. The gasket should match a flat side on one surface and a deep T-channel on the other. Bringing your old gasket or a quick photo to Discount Pool Mart ensures proper matching.
Does this gasket work on unions used at my pool heater or heat exchanger?
Yes — this model is commonly installed on heater unions exposed to high temperatures. If your heater plumbing uses CMP Hi-Temp unions, this gasket is the correct replacement.
Can I use this gasket for high-flow or elevated-temperature lines?
Yes, the elastomer is formulated for hot water and heavy circulation, making it suitable for systems with solar boosts, high-output heaters, or spa-side loops.
Installation, Sealing Behavior & Maintenance
These answers help customers understand how the gasket installs and behaves during operation.
Is installation difficult for the 26200-210-632 T-gasket?
Most replacements take minutes. Remove the union nut, lift out the old gasket, seat the new one with the T-side aligned to the channel, and reassemble the union hand-tight before final snugging.
Will this gasket stop minor leaks around my heater union?
If the union faces aren’t cracked or warped, replacing the gasket usually stops drips immediately. A worn or flattened seal is a common cause of heater-side leaks.
Does this gasket deform under heat?
The Hi-Temp elastomer is specifically engineered to resist flattening and hardening under heat cycles, providing longer service life than standard gaskets.
In-Store Pickup, Service Prep & Replacement Planning
These questions help customers plan their visit and avoid repeat trips.
Is the 26200-210-632 gasket usually available for same-day pickup?
Most Discount Pool Mart locations keep CMP heater-side gaskets in stock during service season. Calling ahead with the part number ensures availability.
Should I bring my old gasket for comparison?
Yes — bringing the old gasket or union tailpiece helps ensure an exact match. Staff can verify the T-channel profile on the spot.
Should I replace both union gaskets at once?
Many technicians recommend replacing both sides of the heater plumbing to ensure even sealing and prevent a second trip later.
