High-Vacuum Inline Filters
Capture oil, oil vapor, and other contaminants from your pump to prevent them from spreading into your high-vacuum system with these filters. When it's time to replace the filter element, you don't need tools to access it; undo the quick-release clamp to open the filter body. Filters have a drain port to remove collected oil.
Filters with quick-clamp connections (also known as KF, NW, and QF fittings) require a quick clamp and a ring (both sold separately) for each connection.
Filters with claw-clamp connections (also known as ISO-K fittings) will connect to larger components than filters with quick-clamp connections. Use four claw clamps and a ring (all sold separately) to secure each connection. Double-claw clamps attach to the grooves on the fittings. Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.
