Regulator Rebuild Questions

[Myrkul]

I'm trying to rebuild some older regulators that haven't even been cleaned in over a decade, and I'm having some trouble finding the correct "o" ring sizes to order.

First up, Gen 1 Bob Long Torpedo Regulator:


I was under the impression that these were fully rebuild-able with standard "o" rings. If you know the sizes or where I can purchase a full rebuild kit I would really appreciate it!

Next up: Macdev Gen 1 Bushmaster LPR



If you know the sizes I need to order or could point me to a rebuild kit I'd really appreciate it.

Thanks everyone!

Update for anyone else who stumbles on this and wants to know (most likely myself in 10 years):

Macdev sonic "O" ring sizes:
Valve Stem: Per MacDev: The seal is pressed into the valve and is non-replaceable. They have some available in Australia for $6 each. Please PM me if you would like to me to add one to my order for you.
Other internal (piston?) "O" ring: #010
Adjustment Cap "O" Ring: #012
Large Exterior "O" ring: #020
Small Exterior "O" ring: #017

Bob Long Torpedo:
Brass Nut "O" Ring: #010
Piston "O" Ring: #113
Lower Shell "O" Ring: #118
Top (duh): #015
Reg Seat: Ordered on from Palmers since they were so damn similar, will update with results.

Found this for your Torpedo. Go to page 12 https://pbmanuals.com/downloads/169_...Manual_ENG.pdf

and the O-ring sizes are under general maintenance a few pages further on. I printed this out a couple weeks ago after buying a Torpedo of Bacci

I think this reg seat will work for the torpedo if you need one

Thank you!!!!

Now I just need that Macdev LPR...should I just scrap it and get a microrock from Palmers?

[Magmoormaster]

Macdev is going to be vastly superior to a microrock.

Not if it doesn't work.....

I’d try to email Macdev or measure the orings if they’re still pliable.

2nd on palmers

So, figured this might help some people out.

Left Bob long Torpedo Regulator Valve assembly. Right Palmers fatty stabilizer valve assembly.
I've ordered the parts shown from Palmers and will update this thread as to compatibility, but just looking at it they look 1:1 and both fit and thread in perfectly.

So the rumors are true... Torpedoes are essentially Stab clones.

Good to know...

I didn't know there was ever a debate about that.

Always heard, never confirmed.

Gotcha.

The Torpedo even copied the Stabilizer's annoying input port location- high up on the reg where it can make removal from a Cocker VASA inconvenient. I put mine on an Impulse instead.

As an aside, you can download an o-ring sizing chart from Captain O-ring

Take it with a grain of salt, especially with old abused rings, but I was able to get within +/-1 size of reality
