## Questions & Answers

**Q: I need an o ring for 10430, any ideas?**
A: Hello, There are a couple of o rings showing when I do a web search on the Kohler 10430 faucet.  I do not believe based on info I saw that the GP30420 will work for you.  If you are looking to replace the large o ring inside the outer housing I believe it is a Kohler K-84100 o ring you would need.  Hope this is helpful.

**Q: I need repair kit for K-12175.  Do you have any?**
A: I am sorry but I do not keep a large supply of parts in stock because the demand in a small town is not worth it. I usually order as needed. I do not have this repair kit. The last one I bought has been used.

**Q: What size is this o ring?**
A: The black O-ring in stock at Security Engineering is approximately 1-3/4" Outer Diameter (OD) and approximately 3/32" thick.

**Q: Where should the lubricant be applied?**
A: Apply the lubricant everywhere the seal contacts the body of the casting.  More is better.  It will also make installation easier.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked Perfectly
*by C***N on June 19, 2025*

Worked great to rebuild my Fairfax by Kohler.It made the faucet like new after I replaced the bushings and o-rings. Comes with ring grease. I replaced the cartridge, too. Like a brand new faucet for low money.

### ⭐⭐⭐⭐⭐ Kohler GP30420 O-Ring Seal Kit - Bearings, O-Rings & Lube - Perfect for Kohler K-10412 Single Control Faucet
*by R***T on October 27, 2013*

This kit was exactly what we needed to stop a leak in our 2.5 year old Kohler K-10412 Single Control Faucet (Brushed Nickel finish).The leak started about a week ago and got progressively worse each day, virtually turning into a river two days ago. These parts were delivered yesterday and, with our 14 year old son's help, we fixed the leak this morning. The job took about 20 minutes total (think we could do it in 10 next time though...), and we also replaced the valve (Kohler GP1016515 Valve for Single-Control Faucets) and the friction ring (KOHLER 1005201 Washer Friction) in the process.One note: We purchased this kit based on responses received to a question posed to other Amazon buyers... and we say thanks to you all for confirming this was the right kit, and for providing great cleaning, lubrication and fitting tips. The two Kohler DIY YouTube videos were perfect too ("Replace the Diverter" and "Replace the Valve").A tip of the hat to you all; our faucet is operating like new once again, in large part to your guidance, and here is what we did:* Turned off the water running to the sink* Put stoppers in the drains on both sides of the sink, just to make sure nothing accidentally went down the drain...* Used a small flat-head screwdriver to remove the plug from the back of the handle, providing access the handle's set screw* Used a small hex (Allen) wrench to loosen the set screw, and then lifted the handle off* Unscrewed (by hand) the covering over the valve (took a bit of 'uumph' to get started, but easy thereafter)* Lifted the faucet ('hub' and 'spout') straight up and off. This was not hard for us to do at all* Thoroughly cleaned the inside of the 'hub' and the handle with soap and Scotch-Brite scrubbing material* Used a pipe wrench to loosen the mounting nut holding the valve in place, then finished loosening and removing by hand* Removed the old valve; the gaskets from the bottom of the valve were stuck inside the faucet, so we had to clean that out* The valve stem sits in a plastic bracket mounted in the handle; we replaced the old bracket with one that came with the valve* Removed the old slide bearings, o-rings and the friction washer and threw them away* Used soap & the Scotch-Brite material to clean the inner workings, especially the o-ring & bearing grooves* Put the new valve unit in place, lining up the posts on the valve to holes inside the faucet for a perfect fit* Cleaned and replaced the mounting nut; hand tightened, then used the pipe wrench for the final quarter-turn* Used the o-ring kit's lubricant to give the noted grooves a heavy coat of that thick, sticky silicone based lube* Lowered the new friction washer into place at the base of the unit* Put both new slide bearings into their grooves* Put a coat of the lubricant on each new o-ring, then lowered them into place in their grooves* Liberally used up the remaining lubricant by coating the outside of the o-rings* Lowered the faucet ('hub' and 'spout') back into place; it was a very tight fit this time (unlike when we took it off)* Used a rubber mallet and small piece of pine 2x4 to lightly tap the unit down the last 1/4 inch... the fit was that tight* Cleaned and then screwed on (by hand) the covering over the valve until finger tight* Placed the handle back on top of the valve, lining up the valve stem with the new plastic bracket we installed* Put the set screw back in place, and hand tightened with the hex (Allen) wrench until just snug* Replaced the plug covering access to the set screw* Took the drain stoppers out* Turned the water back on... looked for leaks... turned the faucet on and tested the hot & cold water flow... moved the spout aroundNo leaks. Like new. Excellent.Was a lot nicer to spend $20 instead of $200 for a new unit.If you have the same sort of issue and have confirmed that these parts are right for your unit, we recommend them very highly.Go for it.

### ⭐⭐⭐⭐⭐ Worked great
*by A***Y on March 14, 2025*

I suggest watching my online instructions before trying to install. That said, the washers worked perfectly. I've been fighting a leek for a long time and didn't realize these washers existed. Replacing the cartridge had no effect. These washers fixed my leak and now the sink works like new.
