Help removing edgun lelya regulator from plenum!

[Steyr]

Have brought a huma regulator and have problems trying to remove the original regulator (red box below) from the plenum. I know it should just twist off from the online huma video but I think one of the previous owners must have screwed it on real tight or used loctite - any tips would be appreciated to remove the regulator without destroying it! Difficult to get it in a vice as its smooth and circular.

I would try using a rubber strap wrench. If you have some tools another useful technique I use is to drill a hole in some wood about the same size what's the outside diameter then cut the wood in half. Then you can use the two pieces of wood as Vise Jaws to hold the circular part without any damage.

Use a leather belt and put it around the reg in the vice.

Strap wrench will do it. Thats odd that its so tight. My reg was finger tight

had tried the strap wrench, but cheapo ebay one tore, the wooden vise trick worked, +1 for that, it must have got seized up over time, need to lube those connections, gentleman

Don't use any petroleum products. Safer to use silicone grease although it's not a great lubricant.
