2 True Things About O-Rings

[NWMNMom]

It pays to plan ahead (I didn't) and it pays to search old threads (I did). My Power Flo pump pot o-ring stretched and I didn't plan ahead and order extra - I will now. BUT I searched old threads and thank you @Bama Rambler . This worked and I ordered two more. Cut at an angle for best adhering

FWIW, I've heard that O-rings sometimes stretch when you pull them through your fingers to lubricate them. Pushing instead of pulling may prevent the stretching.
