Inline Filters

Trap small particles in tubing or pipe to ensure samples are contaminant free for testing applications. Filters protect sensitive process equipment from damage caused by debris.

Clear filters allow you to monitor dirt accumulation.

Filters with a filter-change indicator change from white to red when they need to be replaced.

Plastic filters offer excellent chemical resistance. Brass filters have good corrosion resistance.

High-Pressure Inline Filters

Remove small particles in lines that reach up to 5,000 psi to protect sensitive equipment, such as hydraulic controls. These inline filters act as a secondary defense to trap particles that make it past your intake filter without adding bulk to your line.

Brass filters resist some corrosion. Stainless steel filters resist corrosion better than brass filters.

Choose filters with an access port to install a new filter element without replacing the entire unit or removing it from your line. These filters take up slightly more space than those without access ports.

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.
