Recently purchased 200 saddles to replace current leaky ones,as well as use on all future installs. Current saddles I drilled a 31/64” hole in mainline,now with DSD saddles I can go all the way down to 5/16”. Tried both on a scrap of mainline in the house, thinking smaller hole might be better? All lines have a maximum of 5 taps on them,5/16” tubing on high vacuum. Thanks
