How can I get the encapsulated bolts through the elongated gasket nipples on the gasket?

This question is from Triangle Tank Gasket with Bolts for Most Two-Piece Toilets
Asked by
Mount Prospect, Illinois

July 23, 2014
I'm unable to get the encapsulated bolts through the elongated nipples on the gasket far enough through to be able to put the washer and gasket on from underneath the toilet base on my older model Wellworth toilet. Both my husband and I have attempted this repeatedly both individually and jointly. Even with significant pressure, the gasket nipples won't compress enough to allow the washer and nut to be placed on the bolt—only two or three bolt threads show—and that's just going through the toilet tank without placing it on the base. Please advise how to proceed.

Answer: 
I think you actually have to use your screwdriver and screw them in. That is, you may not be able to push them through all the way. Once you have screwed them in all the way, then you can attach the washer and nut underneath. I actually haven't done this with a new gasket so I could be wrong, but that's what I had to do with the old one that I just took off. Of course, this could be because of age, but Read More

Thanks for the replies. I didn't have time to wait so got the kit to find that it did include the friction ring (white ring) even though it's not shown in the photos.

Answer: 
The triangle gasket kit seals the 3 bolts that attach the tank to the bowl, and it also provides the seal between the tank and the bowl.
It is not related to the parts required to replace the flush valve and/or the fill valve.

After a few choice words, ended up in the trash and a trip th Home Depot for a Kohler part. Worked perfectly.

This tank to bowl gasket did not work and caused me much extra work, Specifically, the center of the gasket has a recess for the large valve nut that does not allow you tighten the nut sufficiently by hand and has very little room for channel locks to grip the nut. With effort, I was able to tighten the nut with oil filter channel locks but the gasket leaked. Finally. I removed the center of the gasket and substituted a standard gasket. I was able to salvage the three tank to bowl bolts with bushings. What a hassle!

Needed this to supplement parts for a "universal" toilet rebuild kit that didn't quite live up to its name. Turns out the gasket provided doesn't actually fit all brands. My kit was slightly different than pictured, with bolts that had plastic coated heads which help seat in the gasket when you tighten them down. It takes a bit of playing around to get the gasket completely seated between the two parts of the toilet, but overall it fits and performs like the original OEM gasket.

Rated 5 out of 5 by from Fixed the Leak Had a very slow leak develop at one of the tank mounting bolts. This kit had all new parts and fixed the leak. The instructions are well written, easy to understand, and anticipate where a novice would go wrong. The instructions make the repair virtually "idiot proof"! Finished the job in less than half an hour.

The product is good, the problem is in the design of the tank and the toilet. As the gasket is new, the rubber works fine even if there is a design problem. The gasket is not supported in any way when installed so I added a piece of the old gasket to create additional support (see picture).

First, the tiolet tank must be drained, then taken apart in a tight space. The tank gasket is unique such that it is pretty much impossible to install it wrong. Next, the tank must be reattached to the bowl. A two hour job easy.

If you have a kohler toilet with flat headed tank bolts, check them. 4 out of 6 were broke on my toilets, heads shear off bolt and it is hard to see unless the head gets moved. New style has a different head and, hopefully, won't suffer the same fate.

Rated 5 out of 5 by from Fit perfectly, easy to install Fit perfectly, fairly easy to align and install and it took care of the tank to bowl leak that I had. The bolts being coated with rubber is a nice addition as the leak I had was caused by the old (all metal) bolts corroding.
