o ring

[GLEN DEUTSCH]

Anyone have any experience with a company called Rehber. They have shift rod o rings cheaper than anywhere I have found. Been burned with scams before.

Never heard of them. If you have the measurements of the O-Ring, McMaster is the place to go – you get a big bag for the price of a couple OMC supplied O-rings. Link below.

Using the size chart, I looked at McMasters, O- Ring store, Graingers and many others. None have the right size. According to the chart, it is an odd size

The OMC 307877 and Sierra 18-7100 O ring specs are .245 ID x .155 thick. Merc/Force/Chrysler equivalent O ring slightly different at .239 ID x .174 thick. No data for Mallory 9-76509 or GLM 45230.

I agree. I have spent some time looking for these in bulk and have not even come close to the right size. I hope somebody has an answer!

Long live American manufacturing!

McMaster has ’em. At least as close as you are going to get. Wanna know a trick? Stack two of them in each hole for an even better seal.

Thanks everybody, esp frankr. I ordered the McMaster. Using two at a time sounds good.

What o-ring are you looking for? The OMC 301877 and Sierra 18-7100 o-ring that Mumbles mentions is for the shift rod. The one Frank is referring to is for the dual hose fuel connector.

Looking for the shift rod O-ring. It is an odd size measured in 1/128 increments. Answering this from work, so I don’t have the numerator .Rehber is the only place I have found some. I think I will just order a minimal number and see what happens. Would be nice to have source that doesn’t charge an arm and a leg

The shift rod O-ring OD is 0.245. #107 O-Ring from Mc_mastercarr the OD is 0.206.
