Cartridge End Caps and Outlet Caps
Optimum® cartridge end caps provide an airtight seal at the top of cartridges. Threaded, self-venting outlet caps prevent leaks and keep air from being introduced into the fluid.
End caps snap securely over cartridge flanges to prevent leaks and fluid contamination. The center push-button presses the cap against the cartridge wall to form a positive, airtight seal. Self-venting outlet caps feature a large ribbed gripping area that simplifies manual installation, along with precision molded threads and a tapered seat that provides a snug, leakproof seal.
