ENVIRO-SAFE ProSeal XL4 Inject Stop Leak R-22 (1.5-5 Ton Units) for Home AC #2100AI-5

Added to my R22 system, so far so good, time will tell if it really seals the system from a very small leak, I believe it might even be the schrader valve

This product was exactly as described but we ended up moving and no longer needed it. This seller quickly processed a return and was very prompt with their reply.

I only had 6" of clearance and injector measured 6.875". The plastic tube section is slightly flexible and i managed to bend it and inject into my 18 year old HVAC system. It needed about 0.5 lbs of Freon for a 7.25 lb system which is up and running again for a few weeks now without freezing up. Time will tell if leak is sealed. PS injector unit will not work in reverse by attaching directly to the HVAC manifold low pressure side connector (no pressure reading or flow).

Description was accurate and it worked just like it should.

I like the convenience of seal in the hose single use.

Very satisfied with my last order that I ordered more.

Would give it all zero Stars non-refundable it did not have the easy seal fluid inside tube

The only problem was that because the product was straight and I needed to get into a tight area, I had to improvise with my hoses to use the 90 on the hose and a male flare coupler to actually introduce the stop leak into the ac system. If it came with a 90 it would have been perfect.
