Leaky flippy caps

[Spring1898]

Well, I had my first taste of flippy caps.
They seem to hold just fine until you rev it up, and then they start spurting gas all over.
Nothing inside the o-ring, or around the cap

Do I need a new cap or a new o-ring?

New cap.

Keep the cap but put a different saw under it.

Years ago when they came out with those caps, I found a way to fix the cap I was having trouble with.
Gently file the outside edges of the 3 cleats or bumps at the end of the cap that goes in the tank. Maybe just a mm off each bump.

If the cap has swelled, these get caught before the cap is fully twisted in place.

If the cap stops spinning then the o-ring gets pulled in but it’s not right and will leak.

This may not be your exact issue, but if it is... this may fix it.

Here is the post-sorry my photo isn’t there now.

I take them off and soak then in a solvent. Works fine for me.

I've been thinking about buying some of them for my 025. Outside of the OP's leak problem do you guys like them over the older style? Or is the leaking a common problem?

Screw caps and flippy caps don't swap. The 025 is screw cap, no?

Thank you. I've seen them listed on ebay. Saved me a couple bucks.

Try @Definitive Dave

He owns CCC and has Flippy eliminator caps. They are black, screw in with 1/4 turn, and eliminate most leaks.

My 10 year old 372 leaks a little out of both caps. Very, very slowly.
Hoping just new o-rings.

I replaced the o-rings and it fixed my MS290

I was very displeased with my Flippy Caps when I first got my MS260. But now that I have figured them out and gotten over being mad at them...they're kinda nice...except when my oil cap leaks. Overall, I am pleased. Very easy to use!

New caps used to be near ten bucks at my favorite dealer.

Now they have dropped to $3.70.

I just buy new ones. [emoji106]

Good to know. I just got a new gasket set oil and gas for $4 and that solved my problem, but if it returns that is a cheap option for OEM

Many times the flippy can be fixed with a new O-ring. Lsss than a buck from some dealers and I have even matched them up at Menards.

I had the oil cap leaking on the MS460 yesterday. Cleaning the o-ring and the seating surface took care of the leak.
