TeeJet Quick Cap Seat Gasket EPDM Pack of 24 — Leak-Resistant Nozzle Cap Seals

If you maintain spray equipment, these small but critical gaskets keep connections watertight and help preserve spray pattern consistency. The CP19438-EPR replacement seats are molded from EPDM, a resilient elastomer chosen for its resistance to weathering and many common agricultural fluids. Supplied in a convenient pack of 24, they’re sized to fit Quick TeeJet nozzle caps and simplify routine service and preventive maintenance.

How does this gasket improve nozzle performance?

A proper cap seat gasket prevents fluid from bypassing the nozzle body and cap, which helps maintain steady pressure and reduces uneven spray distribution. By sealing the mating surfaces, it minimizes drips and loss of product at each nozzle connection. Replacing worn gaskets restores the original fit and reduces the risk of leaks that can lead to reduced efficiency.

• Creates a tight seal between cap, nozzle, and body
• Reduces fluid seepage and dripping at connections
• Helps maintain consistent spray pressure and pattern

What is the material and why does it matter?

The gasket is made from EPDM (ethylene propylene diene monomer) rubber, selected for durability in outdoor and chemical-exposed environments. EPDM resists ozone, sunlight, and many commonly used tank-mix additives better than standard rubbers. That durability extends service life and lowers replacement frequency under normal agricultural and turf applications.

• EPDM offers strong weathering and ozone resistance
• Performs well with many non-oxidizing spray solutions
• Stable over a wide temperature range for field use

How do I install these gaskets and when should I replace them?

Installation is straightforward: remove the old cap seat, clean mating surfaces, and press the new EPDM gasket into the cap seat groove until flush. Inspect gaskets during routine nozzle service or if you notice leaks, pressure fluctuation, or uneven spray patterns. Replace gaskets showing cracks, permanent deformation, or hardening to restore a proper seal.

• Clean parts before installing new gasket for best seal
• Press gasket fully into cap seat groove—no adhesives required
• Replace when hardened, cracked, or leaking is observed

Will these fit my existing Quick TeeJet nozzles?

These cap seat gaskets are designed specifically for Quick TeeJet cap assemblies; they match the dimensions of standard Quick TeeJet nozzle caps and bodies. Confirm the CP19438-EPR part number against your nozzle cap model to ensure compatibility. If you use Quick TeeJet components, this pack of 24 gives multiple replacements for a single service session.

• Designed for Quick TeeJet caps and corresponding nozzle bodies
• Pack of 24 supports servicing multiple nozzles at once
• Check part number CP19438-EPR for compatibility assurance
