Four Seasons 26775 Cap & Valve Air Conditioning System Seal Kit

Excellent product and a great price. Thanks!

Great Product, Works Perfect for our needs and easy to use.

Finally this kit stopped my leak would definitely recommend it!

Good fit and quality. Easy install

This kit stopped my leaking high pressure side service port valve (large, aluminum, male coupler in photo; used on most GM high pressure sides). And the Schrader valves (3 smaller contraptions) stopped my low side service port leak... The low side service port Schrader valve can be removed and replaced with a R134A ‘zero pressure loss’ Schrader valve remover/installer with out the “extra” steps the high side requires... Unfortunately, if your high side port is leaking you must recover all the R134A refrigerant before you attempt to replace the high side. There is NOT a replaceable part in the large aluminum service port. When you remove the large service port, you need a high side service port, octagon socket (Some Fords have similar service port coupler, on the low side and there is a special socket for it as well) to remove it. Sure there are ‘other’ DIY methods that might work, but I wouldn’t install a new one using other DIY methods. And no, an SAE or Metric socket won’t fit. So now you have removed the high side service port coupling, lubricated the seal with manufacture specified AC system oil and installed the new coupler, the system was exposed to atmospheric conditions (air and humidity are bad!) You must replace the receiver/ dryer (contains non-replaceable desiccant that removes any residual moisture AFTER proper evacuation) and acts as a holding area for your manufactures specified AC system oil (yes your going to need manufactures AC specified oil too.) How much and what kind depends on your manufactures specification for a receiver/dryer replacement. Next, you must evacuate the system (using an HVAC vacuum pump or an R134A compatible recovery, evacuation and recharging system) to remove air and moisture. While your at it, replace those plastic service port caps! While they keep debris out of the ports, they play a role in sealing those pesky Schrader valves. Note: You can’t fix a leaky Schrader valve with a new cap! You can’t seal a new Schrader valve or service coupler with an old cap! They work hand in hand.

Good A/C parts replace no problem

I ordered this for my 2002 GMC Sierra 1500 RWD truck. The high side line port was leaking and the only way to fix it this​ by replacing the entire valve gauge port. The old one screwed right off with a pair of pliers and the new one screwed right in. There is no standard wrench that fits it (maybe a specialty wrench that does?). But a pair of pliers worked well. There is red thread lock on the fitting so torquing is not necessary. I also used the shrader core that came with the kit for the low side port. Both worked well in regards to evacuating and charging the system

Fit fine and no issues installing on my truck. Don't forget to pick up a valve core tool for the low pressure side, as most of the regular ones for tire valves won't get the job done.

Relative quick delivery, easy simple install. Extras are always good to have on hand.

Se compró está pieza por qué necesitaba reemplazó. Solo duró una semana y volvió a fugar. Y se optó por comprar un repuesto de fabrica

Good

worked well
