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.

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.
