O-Ring for Flojet 3" coupler

[Shellback1]

O-rings for 3" connection on Flojet waste pump.

The O- on mine is loose and falls off when I put it away, so I tried to find one to buy. I searched the Internet for 2 days. I even wrote a note to Itt Corp - FloJet RV with no response. So I took out the micrometer and inside outside calipers I haven't used in years and measured the original ring. Found this site that has O-rings MSC Industrial Supply Co. . The size I ordered comes in a 5 pack for $3.50 but the shipping is steep $10.98. Well now I can give 2 to my brother who has a Flojet also. Nice tight fit!

Here is what I ordered:
