In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
when to use NPT and when to use sweat
I need 2 sets of circulator isolator flanges. There are two different types: NPT and Sweat.
Usually when we should use NPT and when we should use solder?
Do you think this isolator flange from Taco is good? http://www.sdsmarket.com/Taco_SF_100S_Shut_Off_Swivel_Flange_1_Sweat_p/sf-100s.htm. It seems different with others.
