Regulator Leak Repair

[Richard Dowling]

Anyone ever pulled a reg apart? Just found a leak on this solenoid inlet connection. I'm a little nervous about pulling it apart just Incase I don't put it back correctly and end up shooting the thing across the room at 200mph when I repressurise.

Looks like you can just twist it right off? The silvery block is just the solenoid by the looks of it, so you're not actually opening up any of the inner workings. If it leaks there it's probably due to a faulty o-ring, washer or grommet or something like that. You can take it apart, replace the faulty bit and put it back together.
I recall reading you shouldn't use the white PTFE tape to fix leaks like this... although your solenoid is probably mounted after the regulator and only has to deal with low pressure, it's still better not to use it. Covering 1 broken part by using something else will only get you so far. Better replace the right part

Put a spanner on it and tighten it a little more. If it leaks again take it apart, some have an aluminum gasket others have thread seal locktight 243 thread lock will do the job I've put fittings into pressure vessles with it. Normal ptfe tape is no good for gas fittings but you can buy ptfe for gas.
I'd use threadlock its more reliable
