CB Series Screwed PN40 Flanged, and Class 300, Y-Type Strainers feature screen chambers that won’t leak or crush. Both ends of the chambers are precisely machined. This means perfectly round and smooth seating surfaces, as well as a fixed chamber length. Since the screen seats snugly on the machined surface, no particle bigger than the screen opening can escape around the end of the screen.
Straight threads mean it takes less torque to achieve a tight seal with proper gasket compression. Less torque is also required to remove the retainer. For you, that means less danger of “freezing in” than with hard-to-break tapered pipe threads.
Many screen materials, meshes and perforations are available.
