Default Does anyone make fuel caps?

Hi all!
Does anyone make fuel caps for RVs? The kind that you can open without using a screw driver?
I know I can loosen the nut and put some fuel lubricant on the seal. I don't know about loosening the nut though - I will start worrying about leaks.

Thanks!

Thumbs up Fuel Caps

These are great. I have them on my RV-4.

Default Andair option

Here is another good looking, somewhat more expensive option from Andair.
https://www.aircraftspruce.com/catal...airfuelcap.php

FYI: If you don't need the locks, there are number of small fuel cap opening tools that you can buy or make that fit nicely on a key ring (smaller than a car key, much smaller than a screwdriver) that work without scratching the surrounding paint area. Some use a small craftsman-brand 3/8 inch wrench, where the open end handles the lever on the cap and the box end goes on your keyring.

This and replacing the hard Viton o-rings with soft durometer silicone o-rings makes them work like butter.

Thanks, Bob, I am surprised the silicone o-rings work with fuel, but clearly they do. Nice mod.

BTW - I have been using DC4 and it dissolves off and gets stiff again quickly. Lately, I use my fuel dip stick and a few drops of fuel on the Viton makes it operate very smoothly - - - once. I ordered some Krytox (a pure PTFE paste) to see if that will retain it's lubricity.

Bill not sure why you think red silicone o-rings don't work with petro fluids, but they do although I'm sure Viton is a better choice, but not available under 70 durometer. I work around the corner from an o-ring distributor. I walk in, show them what I want, and they hook me up. In this case I handed them a fuel cap and told them I wanted softer o-rings.

Can you post a Part Number for the O-Ring so that we can find a source on the internet that sells them?

A quick Google Search came up with this. Will it work?

I have the newton caps on our plane.

They're locking, really like them. My only issue was getting keys.
