Flange to port adapters allow the mating of a KF (QF) flange to a particular type of port or tubulation. All of our flange to port adapters are manufactured from 304 series stainless steel (unless otherwise noted).
Flange to Port Adapter Types:
KF to 1" Baseplate Port -- Adapter fits through a 1" diameter hole in a baseplate or chamber wall used for connecting a roughing pump or other KF flanged component to the chamber.
KF to Hose Tubulation -- Available in either stainless steel or aluminum, they connect a KF flange to a plastic or rubber vacuum hose
KF to Test Port -- KF flange terminating in a tube with an O.D. that fits either a 1-1/8" or 2" O.D. test port
KF to Welch Pump Port -- Substitutes for the regular intake hose coupling on the pump. Threads into the pump inlet, enabling direct connection to the foreline by the KF flange.
NOTE:Welch pump port adapters are available in both new style (oil sight glass pressed into pump body) and old style (oil sight glass held in place with a bolt ring) due to pump design changes by the manufacturer. Please pay careful attention when ordering.
