This adapter converts a KF-50 flanged fitting to a 0.625 in. compression port. Compression ports are typically used to make quick connections to tubes and half nipples, commonly found on gauges, instruments, and gas supply lines.

"SWIFT-SEAL" KF adapters create a leak-proof seal when the knurled ring is tightened, allowing the uniquely shaped inner ring to both wedge and compress the O-ring circumferentially around the tube. An inner circlip can be re-located to any of the 3 indexed slots (or removed altogether), to make fast, repeatable tube insertions into the adapter; required for repeated, quick changeouts. All components can be easily dismantled for routine service. SWIFT-SEAL adapters are made of 304 Stainless Steel and anodized aluminum.
