The Stenner ST138 is a weighted suction line strainer. This line strainer is designed to keep the suction end of the tubing full of media while the weight of the strainer ensures that it remains at the bottom of your tank drum. By increasing the suction power the Stenner ST138 allows the pump to consistently maintain prime even when the pump is not running.

Features:

• The Stenner ST138 ensures a clean system. The ST138 keeps your tank and pump clean and efficient by filtering out larger particles that may be present and could cause potential damage.
• The Stenner ST138 does not disrupt your pump system. The ST138 is weighted and will remain at the bottom of the tank drum. The line strainer is placed on the suction side of the pump for optimal performance.
