Shaped Honda carburetor float bowl rubber gasket for CB350 twins, CB500/550's and a few others as well as some Kawasaki's. Save yourself some time and frustration by getting the proper shape gasket for the float bowls. This is made from viton rubber so it will not swell after coming in contact with gasoline.

Sold individually. We also have a set of 4 available here.

Note: This will not fit carburetor model 350A, 3B and 3C which were used on the early 350 twins in 1968-1969, see the details in the fitment list.

Works well, sits well, no leaks

Rubber gaskets seals as it should. Never leaked, and I had since bought a few more for to rebuild other carbs.

Carbs

Haven’t had any problems with the gaskets. They have worked perfect on my 350 twin

Perfect Fit, but...

Posted by David on 4th Mar 2016

Perfect fit for my 72' CB350 twin, but these WILL swell after contact with fuel. Make sure to order extras for multiple carb adjustments when doing performance jetting.

float bowl rubber gasket

great product easy install

Much better then the gaskets that came in carb kit.

Posted by Bryan Hersman on 27th Feb 2015

I tried for 20 minutes to get a un-shaped O ring to stay in place during installation. After the first one I went to 4into1 and ordered these formed rings. I wanted to start the bike so I continued and struggled with the other 3. The bike did start but had a good leak from one of the bowls where the round gasket didn't stay. Luckily a few days later these came in and in 2 minutes I had the leaker out and the new formed one in. I then had to adjust a few floats so I changed out the others as well. Do yourself a favor and order these formed gaskets in the first place.

Had no issues, easy to install, and best of all: no float bowl leaks!
