Del Mar Big Blue Style Point of Entry Housing & Cartridge

Sale price Price $60.00 Regular price Unit price  per 

The Del Mar Big Blue is a primary component in water filtration systems, is made from a durable, reinforced polypropylene, and resists corrosive effects from a variety of chemicals. Topping the housing off is a high-flow polypropylene (HFPP) cap with a 1 1/4" internal port that allows water to pass through rapidly. This coupled with the already larger-than-standard filter capacity make Big Blue Housings popular choices for high flow applications. The extra-wide housing accommodates large 4 1/2" wide filters for increased flow. This housing does not have a pressure relief button on the cap.

This system includes housing and replacement cartridge ONLY.
