GREAT FIX

Posted by Unknown on 21st Mar 2023

WORKS GREAT
Fixed the problem (again)

Posted by Dr. Dave on 24th Oct 2022

Seems like it costs just a little too much, and shipping too, but it fixed the problem. Same thing happened 5 years ago, so this is the 3rd time. Rubber at the periphery seems to thin out and fail, it starts leaking and won’t allow full pressure. I wish it was just $10 including shipping, but glad they're still available. This regulator is still the best and longest lasting one I’ve ever had. Homeowner use, not commercial, pump only runs every 2-3 weeks for a short period. I think the last time was warranty replacement and was free, but I can’t remember. Customer service is excellent on their website. The plastic knob also failed recently, so i was using a visegrip on the metal shank to turn pressure up and down. Replacement knob unit not worth the price. Then when I was replacing this I found the old knob assembly, so i switched that out too.

Diaphragm in pressure regulator failed after many years

Posted by Don Daubert on 23rd Dec 2019

The diaphragm in pressure regulator failed after many years of use. Contacted Pneumatic Plus. Answered a couple questions and they were able to determine replacement part needed. Parts arrived on time. Back in business!
Thanks Don
Excellent customer service

Had a PneumaticsPlus regulator in service for many years. Occurred a slight leak and contacted customer service. He directed me on ordering an exact replacement diaphragm and unit works flawlessly again. Outstanding customer service. Highly recommend PneumaticPlus products.
