  • Valve Stem Size: 5/16" (.3125") diameter
  • Material: PTFE for superior heat resistance and durability
  • Quantity: 12 seals per set
  • Positive seal design for consistent oil metering

Features & Benefits:

Great Transaction. Easy to use website. Nice experience. Free candy is nice,, too.

Simple to order!

Ordered Sunday and recieved product Tuesday .. What more can u ask for? Great Seller!

The Best Pricing online period! The shipping was very reasonable with great communication and tracking number proviced. My parts were boxed well and arrived right on schedule. This was my first purchase with Autoplicity but will for sure not be my last.

I ordered a bike rack and the rack was shipped promptly, and was exactly what I ordered. Best price on the internet

Had a great first experience with Autoplicity. I ordered my package late in the day on Wednesday and it was at the front door Thursday! Another big plus is that their prices are hard to beat. Won't have a problem ordering from them again!

Product was shipped super fast. And product was in a well packaged box and everything was there. I would do business with them again in the future. Highly recommended and lowest prices!!!
