Most Liked Positive Review

Gasket Replacement

Just what I needed to replace a old one that was falling apart due to have to steel wool the Flame Sensor Rod every Fall. Would be best to ship these in a small box or at least some stiff cardboard due to getting creased in the shipping and sides of the gasket get folded thus break off.

Most Liked Negative Review

These are complete garbage

The replacement gaskets disintegrate in your hands like ancient paper. I Destroyed two of them trying to open the package they come in. If you are lucky enough to get one out of the bag unbroken then good luck trying to get the two sensors out through and mounted on the boiler. I had to tape it to the boiler then try to carefully slip the sensors through it and put the cap on over the sensors. I still ended up tearing the middle out of the last one I had but had to use it. Clearly whoever builds these has never installed one or they would make a better product. Total garbage!!

Just alright.

I feel pretty neutral about this product. we ended up ordering 10 of them because something that regularly gets serviced and they usually tear every time you take them apart the product itself is an oem part that is just cheaply made. Luckily they are cheap and we're readily available by supply house

Gasket Is OE, packaged poorly for shipping

Yes These Are Fragile. I Have Ordered Several Amd Had To Have Each One Resent Due To Them Areiving Folded/Torn. Other Reviews Seem To Corroborate This Same Problem. SupplyHouse Really Needs To Change How They Handle These.

I would NOT buy this item again

The gasket was so thin and fragile that the first one I ordered arrived broken. The replacement gasket arrived okay but fell apart when removed from the plastic bag it was in. Too thin and fragile to use

Gasket was 100% correct

When buying replacement gaskets, slight differences can determine if it is useable or not. This one was perfect

Poor packaging

The product was fine, but it if very fragile and was sent in an envelope, without anything to stiffen it. The gasket was broken when I received it.

Not a good product

Replacement gasket for the ignition rod. I bought 3 and was glad I did. One was broken in half at delivery and the second one started to break apart on installation
