ROTATABLE, BOLT-REVERSING
8 CF, 6 CF, 4½ CF AND 2¾ CF UHV COUPLERS
JOIN TWO TAPPED-HOLE COMPONENTS CLOSE TOGETHEREMITTERSION GUNSTHE ROTATABLE CLOSE COUPLER
Rotatable Close Couplers are two-port Multi-CF Fittings,
consisting of machined thick-wall cylinders, with opposing
same-sized CF sealing surfaces (2¾, 4½, 6 or 8). The ability
to rotate the two surfaces allows for increased flexibility inassembling fittings and in adjusting systems after assembly.
The Close Coupler minimizes overall length in joining twotapped-hole components, resulting in the shortest possible
distance between them. Under the bolt heads, flange
thickness has been decreased, while adequate rigidity has
been maintained through the use of an appropriately machined
thick-wall cylinder. Care is needed to use the correct bolt
lengths. All 2¾ CF, 4½ CF, 6 CF and 8 CF sealing surfaces
have a pair of Grabber Grooves to allow internal apparatus
mounting.
