Stainless Steel Quick-Clamp T-Strainers

Add these inline T-strainers to your sanitary process line to trap solid particles during clean-in-place (CIP) cycles. They have quick-clamp sanitary tube connections, also known as tri-clamp connections, for use in dairy, food, and other process lines that require frequent cleaning and disassembly. As the high-pressure cleaning fluid flows through your line, the strainer's screen catches particles larger than 1/8" to prevent damage to pumps, valves, and other downstream components.

Compact T-Strainers

With a smaller overall size than T-strainers of the same pipe size, these are well suited to applications in close quarters.

Temporary Inline Strainers

Remove debris from new pipelines before installing equipment. Sandwich strainers between two flanges with the cone pointing in the direction of flow.

Low-Pressure Inline Strainers

Easy-Swap Stainless Steel Basket Strainers

Made of 316 stainless steel, these basket strainers have better corrosion resistance than iron and bronze basket strainers.

Easy-Swap Bronze Basket Strainers

Bronze basket strainers are stronger and more corrosion resistant than iron basket strainers.

Bronze Basket Strainers

Bronze basket strainers are stronger and more corrosion resistant than iron basket strainers.

Stainless Steel Basket Strainers

Made of 316 stainless steel, these basket strainers have better corrosion resistance than iron and bronze basket strainers.

Self-Cleaning Metal Basket Strainers

Spend less time on maintenance—these strainers have an inverted basket that allows debris to fall into the drain as it collects.

ASME-Code Metal Basket Strainers

These basket strainers are constructed for use with boilers and pressure vessels.

Sanitary Magnetic Strainers

Draw metal shavings and other contaminants out of your sanitary liquid line with these strainers.
