The Hunter Seal of Approval

Manufactured from the highest grade UV resistant materials, the Institutional Spray and Pro-Spray's® pressure activated, multi-function wiper seal is designed for long life under the toughest conditions. A zero flush seal ensures dependable operation without excessive "flow-by," allowing more sprinkler heads to be installed on the same zone. A unique pressure activated design grips the riser when operating and keeps debris from entering the seal when retracted. And, an additional riser seal support helps to ensure strength and reliable performance. Plus, each seal can be field-replaced without having to replace the body cap. Now that's a seal you'll approve of.
