Re: Gasolator Correct Drain Valve and Gasket Seals

I am posting a response I made to a Member who wished me to confirm which gasket I had found successful for the gascolator.
YMMV
Question:
Hi George,
Is this link still the right gasket to use on 170B with the glass bowl? I hope so, as Cessna has lost their mind at nearly $35 each.
Thanks,
(The link provided is to Aircraft Spruce PN: 05-01059, labelled a “Fuel Cap Gasket, FC2651, priced at less than $2)
Response (Don’t really want to label this as an “Answer”:
That is the one in mine and it is what I buy each year at annual inspection, PN 05-01059 (also known as FC2651, Fuel Cap gasket. It fits the gascolator, the fuel cap, and the engine oil cap.)
The dimensions for part # 05-01059 are: 1-1/2" ID, 2-1/4" OD, 1/8" Thick.
There are others which “can fit” but I don’t like them.
Examples:
06-02052, Oil Fill Cap Gasket, (also known as the TCM 533355 Oil Fill Cap Gskt),
05-11187, Gascolator Gasket, I don’t like the smaller, I.D. At 1-3/8”.
05-11191, Gascolator Gasket, I don’t like, Too Thick at 3/8”.
The Koehler K2250B gascolator used on the 170 A/B is the original. Garwin made an almost identical replacement which I mention just in the off-chance yours has been replaced. I have not tried any of these gaskets on a Garwin (and have no excuse because I actually have a NOS Garwin in my stockpile. (You never know, I may need to ransom a grandchild from China some day when they take-over the rest of aviation.)
Certainly, these options are all less expensive than Cessna Genuine Parts, which are made of a white rubber which hardens and becomes brittle after a year. The ones I replace each annual (05-01059) are still flexible and show no signs of deterioration. (Note: They claim it is not suitable for auto-gas. While I once-upon-a-time used MoGas for a short-hop of desperation ... {Disclaimer: I landed at Ol’ Gar’s place over on Toledo Bend LooEasyAnna and being the cheapskate he is, had no AvGas available... so I put in 5 gals of Shell in my right tank, took off on a short hop to Center, Tx for real AvGas, making sure to switch to that right tank to burn that MoGas out ASAP and filled up with cheap AvGas.).... I didn’t notice any difference in that gasket after that short exposure.)
Hope this helps.
