HVAC Valve Cap Kit
This 48-piece set supplies R134a and R12 charging-port caps in four sizes: 10 x 13 mm, 10 x 16 mm, 10 x 17 mm and 10 x 17.5 mm. Each cap includes a rubber seal and is made from pressure-resistant, corrosion-resistant plastic for automotive air-conditioning service work.
Suits DIY AC maintenance; not for threaded ports
The caps press on without threads, so they fit standard R134a service ports on most automobiles. They will not work where a screw-on cap is required. Buyers needing threaded seals or non-R134a/R12 refrigerant systems should look elsewhere.
Verify port type and dimensions before ordering
Confirm your vehicle uses R134a or R12 refrigerant and that the service ports accept non-threaded press-on caps. Measure the port outer diameter to match one of the four supplied sizes. The caps are new and ready for immediate use.

Questions about this item
Will these 13 mm 16 mm 17 mm and 17.5 mm caps fit my R134a service ports?
The kit includes four sizes covering 10 x 13 mm 10 x 16 mm 10 x 17 mm and 10 x 17.5 mm ports used on most R134a systems so one should match your vehicle
Can I keep using my old screw-on caps together with these push-on caps?
These caps are not threaded and rely on an internal rubber seal so they cannot replace screw-on types and should not be mixed on the same port
How do I know each cap is sealing properly after I push it on?
Press the cap firmly until the rubber seat contacts the port face then check that no refrigerant vapour escapes and the cap stays in place when tugged lightly
