Re: Baxter Cycle Tap Plungers

Postby pauldridge » Thu Mar 21, 2019 2:33 am

After going through 3 sets of replacement plunger corks, none of which were leakproof, and almost impossible to slide as well, I broke down and bought a set of beautifully machined-from-brass o-ring plungers from Baxter Cycle in the US http://www.baxtercycle.com

Each unit is $20 US and comes with some sort of o-ring lubricant for inserting into your petcock. The first thing I learned is that the plungers/o-rings were too loose to properly fit into the cheap Chinese knock-off petcocks I had purchased a while back. Fortunately, though, I still had my original Ewarts petcock saved in the parts bin. The plungers fit perfectly, require almost no effort to open or close, yet neither has leaked a drop so far.

My only complaint is that they didn't provide a set of replacement o-rings, just in case, as I had already found that size is very difficult to come by with my local bearing/seal house.

If I were ordering again, I'd probably ask for a spare o-ring with the deal. Otherwise, I highly recommend for what looks like a long-term solution for a perennial problem.

Here's the direct link to the product: https://www.baxtercycle.com/product/push_pull_petcock_plunger_insert/

I also needed one to fit in the Ewarts tap required to fit between the tank and carburetor on my Competition model Gold Star. I only need one but bought two to have a spare. But, then I found that shipping was free for orders of $50 or more so I bought a third one for a cost to me of only $11.50 (or, the one I actually needed cost $60, depending on how you want to look at it).

The plunger works great.
