Rebuild CO2 regulator?

[Trey]

I am running a CO2 art regulator and the needle valve has gotten to a point where I have to interact with it almost daily. It tends to slow the flow down over night, sometimes even ceasing flow all together. Sometimes if I just lightly tap the adjustment knob it returns to flowing normal, other times I have to actually turn the knob. This happens almost nightly.
Any advice?

I don't have much experience with this but, obviously, this shouldn't continue. I would invest in an upgrade.

Copying @Alanle who has more experience with regulator builds.

Thanks Art. I certainly want to get it ironed out. The regulator worked great for over a year. I feel certain their is a seal, or hole that needs to be cleaned or tightened. I was just hoping someone here had dealt with this before.

I have a cheap one that drifts. If I push in on it the flow changes. I think the cheap ones have a rubber cone that gets hard and expands and the coarse threads on the adjustment screw allow it to move in and out. As the rubber wears out over time it gets worse. I haven’t torn mine apart so I can’t say for sure, just basing my suspicion on working with old outboard carburetors and seeing the same symptoms with fuel flow

I have a Victor HPT270C regulator. It’s a chrome plated medical grade regulator. I don’t think there is any substitute for getting a quality regulator for the reasons mentioned. Not to mention, they are very affordable if look enough on eBay. I snagged mine in like new condition for $60.

What is the warranty period for it?

the pro series has a 5 yr warranty

the pro elite series I bought had 10 years.
