Who invented the ProSeal XL4 Inject? Enviro-Safe's own Vice President, Randy Price. 

Can I inject Enviro-Safe ProSeal XL4 Inject into my system while charging with refrigerant? Yes, you can use the refrigerant being added to push the sealant into the low side of the system.

How large of a leak will ProSeal XL4 Inject repair? If the leak does not empty the system within 72 hours, ProSeal XL4 Inject #2100AI-5, will typically seal the system. (This information does not apply to industrial systems.)

Can I refill the ProSeal XL4 Inject? Absolutely not. The ProSeal XL4 Inject is a one time, one application use.

Will ProSeal XL4 Inject clog Schrader valves? ProSeal XL4 will seal the Schrader valve if it is leaking. However, when reconnecting the charging hose, the seal will be broken allowing the Schrader valve to be used as before ProSeal XL4 was installed.

Will ProSeal XL4 Inject intermix with all refrigerants? Proseal XL4 mixes with all hydrocarbon and chemical (R12, R134a, R502, R22) refrigerants. Do Not Use in Ammonia systems.

Will ProSeal XL4 Inject perform in all systems? ProSeal XL4 Inject will seal most leaks when used according to the manufacturers’ directions. ProSeal XL4 Inject will seal most small holes located in the air-conditioning condenser, evaporator, fittings, and metal lines. ProSeal XL4 will NOT repair O-rings, or seals. Do Not Use in Ammonia systems.
