VTS253B-320 Build Part I
This is the first of a few installments on how to build a regulator. I have been learning as I go along with the help of many knowledgable individuals.
I'll try to make this process as detailed as possible.
Important Edit: I have since started to use teflon tape on all regulator body connection points. Non-hardening thread sealer is okay for the post body, but you may want to consider teflon tape for high pressure connections and to protect the female threads in the regulator body. Once these female regulator body threads are shot, they cannot be repaired. Your regulator becomes a piece of junk.
I have not received all my parts, so like any mechanical job, I like to do all the prep work prior to all the parts getting here.
One thing you'll need is some type of thread sealer. It looks like Victor uses red Locktite on their connections. I found this out the hard way while trying to muscle the 1/4 x 1/4 nipple off the regulator body. It wouldn't budge, and I am fairly strong when it comes to turning wrenches (I can use arm strength to do most car suspension jobs, not that I like to).
Getting back to thread sealer, LeftC (at TPT and Tom's site) suggests the use of a teflon based liquid thread sealer, the non drying kind, so that when it comes time to disassemble you can do so with little headache.
Aqauriumplants.com recommends Locktite or teflon tape.
The other reason for using this liquid type of sealer is because teflon tape has a tendancy to shred and sometime end up inside your regulator, solenoid, or metering valve...
This obviously can cause problems.
I chose to use ARP's thread sealer, which is from my car days:
To get the 1/4" mptx 1/4" fpt nipple off the regulator, I used a 19 mm deep impact socket and my 1/2" impact wrench, which did the job with little effort. For God's sake, make sure your impact wrench is set to reverse, not tighten!!! :lol:
Caution: The use of a vice is recommended. If not, make sure you hang on to the regulator body and not the gauges!
