R410a acessories


Summer is around the corner. I haven't work yet on R410a system. I have Testo 550. I want to buy set of hoses with a ball valve, Core removal access. What else do I need for R410a system?

-Does the service valves for R-410A systems have 5/16" access port?
-Does the R410a refrigerant cylinder have 5/16" access or 1/4" access?

Thanks yall
JJ

Their 1/4 inch, unless your working on a mini split, then their 5/16". The R410A cylinders are all 1/4". Just remember, the cylinder is on a 25 pound cylinder, not 30 like R22.

JJ I'd recommend the regular ends and add on the ball valves. That way if you're like me and just plane hate the things then you can take them off and screw on the low loss.
