27273 Thermostat Seal

The gasket fit but loosely, would you explain why this is? not sure if this is going to be an issue in the future

Stant, and Stant products including vehicle Thermostats, best in the business. Note: Some of Stant thermostats that are sold are without the necessary gasket. It is important to NOT use the existing gasket, even if an existing Thermostat gasket looks fine, because of slight variances in diameters and the mating surface on the Thermostat housing. I used this gasket with a new Stant thermostat, (purchased separately), and my vehicle engine runs cooler while allowing the heat to begin much quicker. I'm not associated in any way with Stant. I just believe their products and this gasket that is coupled with their 195-degree Thermostat, is absolutely the best in the business. 5 stars !

It was delivered before what it said and it was.The product is good I’ll be buying again

fits my 2004 buick Lasbre 3.8 L. stant superstat thermostat perfectly. NOTE... sides are tapered.. smaller o.d. goes down into thermostat housing.. clean out housing bolt holes of coolant with air gun or Q-tip before installing capscrews... a little antiseize on threads... much less expensive than auto parts store.... no leaks..

Fit my thermostat excellently

No creative response. If you need a rubber ring, that's what you get.

Well made, no blemishes, and fit perfectly on our chevy impala LS Love the design of this seal. Unfortunately, the pic fails to let you see what I am addressing. There is only ONE WAY to install it. No mess, no fuss, just works great.

The seal is better then the original, itis designed that it can expand in the housing while compressed (has 2 grooves)
