Pentair Aquatics SMART UV 40 WATT O-Ring Help Needed

[DarthSimon]

Hey Guys,
I purchased the Pentair Aquatics 40 Watt UV Sterilizer and received this weekend.
Picked up from BFS. I am unfortunately missing the smaller o-ring. It's number 4 in the manual.
Does anyone here know if it's a standard size and thickness so I can run over to Depot and pick one up?? Can't seem to find any info on size??

Thank You in Advance,

Give pentair a call, their support is awesome. I accidentally glued the union wrong, thought I was in deep doodoo, but the guy on the line knew his parts like the back of his hand and I got the part asap. It's a commercial product /company, we're just lucky to be along for the ride. Order a replacement bulb while you're at it as you'll need one eventually. I also picked up a rebuild o ring kit as uv is really hard on them. Not terribly expensive either like some companies which charge an exorbitant amount for repair parts (here's looking at you Mr. 30$ jbj chiller nipple)
