How to remove the end cap from an FX air tube?

hasenpfeffer · Oct 22, 2016

I tried removing the brass valve end from my FX Cyclone air tube so I can install a regulator, but it's stuck on tight. It looks like it's supposed to come off easily in YT videos There's a hole on the side meant for inserting something to gain leverage. I used the largest allen key that would fit, and I only managed to bend the allen key and deform the hole.

I've released all the pressure by fully depressing the valve, so that isn't the problem.

Any tips for getting a grip on the brass without marring the finish too badly?

I don't know the correct name but I think it's a "Pin Spanner" you need. Semi-spherical spanner with a pin which engages that hole (the spherical..er..ness is meant to match the tube or valve diameter, of course.

However, I also think

a strap wrench will do the job, if you can get it onto the valve brass rim.

PS. an old leather belt can be made into a strap wrench quite easily.

My cyclone was hand tight. I would use a little bit of heat on the tube. Be prepared to replace that oring. If I remember right it is a weird size but I probably have a couple laying around if you need one.

If you don't have a pin spanner wrench you can get a taper pin to fit the hole and use a box end wrench on the pin for leverage. Ever use a box end on an Allen wrench same idea

Thanks for the suggestions. I got it apart by putting an allen key in the hole, bracing it in a padded bench vise, and torquing it with both hands. The o-ring was a little chewed up, like it was sitting on the threads when it was assembled. I won't be needing the o-ring with the reg I'm installing.
