The 2 gauges were replaced fine, but he reducing valve body is very flimsy
The reducing valve body is very flimsy. When I tried to fit it with a standard wrench, the body got a fine hairline crack. How is this possible?

Hi Joseph,
Thank you for your review. Please accept our apologies for this situation. We will be in touch with you shortly regarding your order.
Packaging
When I received my pressure gage, not only was the nipple with threads was the wrong size, was 3/8" and not 1/4", the lens on the gage was cracked. It was packaged in an ordinary small bubbled envelope which did not protect the glass on the gage.

Screwdriver, Pliers, Socket set, Wrench Set, Nutdriver, Adjustable Wrench, thin open end wrench..2 dfferent sizes needed.
Tag / label everything you remove ... be careful , be patient removing and replacing what you need to replace or remove or transfer to your new part.... Mark, tag, color coat wiring and switch for easy reassembling... A vice/ liquid wrench and loctite is useful to have on hand. Take your time it took me two (2) hours straight from start to finish... 2 Thin open end wrenches needed to remove gauge and nipple.... hope this helps.

1.) Carefully removed old air chuck,pressure gauges, and 3/8 double threaded piece from pressure reducer and cleaned threads of any parts that you intend to re-use, like in my case,the air chuck and pressure gauge that screws into pressure reducer with brass wire brush.
2.) Wrap each threaded piece clockwise with Teflon tape.
3.) Before installing new Pressure reducer, pay attention to arrow on bottom of reducer...this arrow should point toward air chuck when installed correctly.
4.) After CAREFULLY threading all parts back into reducer(you DO NOT want to put a lot of stress or pressure from a rubber jawed vise or vise-grips) on the reducer, so only tighten 1/4 turn past finger tight, or you will break the reducer...this thing is made from cast!)
5.) Reinstall complete assembly and check for leaks...done!
