I need to stock up on the common sized o-rings. Primarily for my high pressure line quick-connects. What size o-ring should I get to cover the connectors before the gun with 3/8 line and past the gun (which I know is a smaller quick-connect).
I hope this makes sense. Thank you!
If using hot water…1/4" Couplers (25) Pack Viton O-Rings - Pressure Tek
If not…1/4" Couplers (25) Pack Buna O-Rings - Pressure Tek
Thanks Gary - I hope you are doing well!
Go to Harbor Freight and buy their Viton o-rings assortment. Should cover just about every size you need and then buy a pack of 1/4" and a pack of 3/8" Viton o-rings from PT or whatever supplier you like.
Like everyone else said…I just keep a stock of 1/4" & 3/8" that I get from my QC supplier. We never use hot water, but stick to the viton anyway.
The assortment from Harbor Freight is a nice thing to keep on hand. Your reels have o-rings in them as well as check valves in pumps and proportioners do too and you never know what size you need until you crack them open and pull out the old ones. The assortment kit covers probably 95% of that stuff. The only ones I know don’t come in the kit are the larger ones for the swivels on your reels.
