10" (#10) replacement sump fits all Pentek 3G Slim Line (SL) caps. Pentek uses the same thread pattern for all 3G Slim Line (SL) #10 & # 20 filter housings (blue, clear)

Note: Clear Housing Sumps are more prone to leaking and cracking, and are not as resilient as their opaque counterparts. They may be significantly less able to handle high pressure, temperature, exposure to sunlight, and other stress. We highly recommend considering a black, blue, white, or grey opaque housing sump, especially if your system is operating under high pressure or temperature conditions. Fresh Water Systems offers heavy duty polypropylene filter housings in a variety of sizes and colors.
