COMP Cams Valve Seals
COMP Cams offers a complete line of valve seals, from the stock GM O-rings to the positive-stop PTFE seals. They are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The O-ring seals use the standard retainer and oil splash shield. The umbrella seals are normally used when a larger-than-stock diameter spring is used. In the case of a double spring, the positive stop PTFE seals are used. For triple-spring applications, use the smaller-diameter Viton seals.

Kinda of a cool gadget
Color: Cool White
I really didn't know I needed this until I got it! Easy and quick to recharge batteries (they do not come with rechargeable batteries). Put out enough light for an evening outside around the table

Love the Warm Glow!
Color: Warm White
This light is very easy to install and has 3 different lighting options. I love the warm white light it emits as opposed to a bright white light that could attract bugs at night. Perfect light for patio, deck, camping, golf cart, etc!

It feels cheap and works just okay
This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!
Color: Cool White
This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.

Doggo approved!
Puppy said, "Yes, please." She's a large breed and chews through some toys like nothing. It is May now, and this one is still standing strong. It doesn't have any pieces coming off, so it's quite hard and safe, nothing is coming off for her to eat. It is really resistant to chewing from a Great Pyrenees, and for the price you can't beat it, as it will last months.
