1-1/2 x 1-3/4 x 1/8 Viton O-Ring (3 Pieces)

I use this as a high-temp replacement for the OEM CAS o-ring in my NA Miata. So far so good. It's been in a couple of weeks and no leaks! Just as described.

1 of the 3 rings in the bag already had small cuts in it.I used these rings as a 1990 Mazda Miata MX-5 Cam Angle Sensor "o-ring".The ring I used seems like it did not properly stop the oil from dripping, BUT it might have been my fault. I played around with the CAS a lot before I finally completely inserted the damn thing. I will replace the o-ring again, and ensure I do it properly this time, without brute forcing it in.Value 10/10Durability 6/10 because 1 o-ring already had cuts in it straight out of the package.

Great price and fit head, water and fuel caps on my boat perfectly!

I slapped this bad-boy in the back of my engine at the CAS sensor and now it stopped absolutely PISSING oil.SOLID PRODUCT.
