Pentek - Standard 10" 3G Filter Housing - Black Cap/Blue Sump - 3/4" NPT
3G 10" Filter Housing with Black Cap & Blue Sump
The Pentek 3G Slim Line housing represents a practical evolution in filter housing design. Built from durable polypropylene with a reinforced cap, this 10-inch standard housing features buttress threads for easier cartridge changes, integral mounting brackets, and a top-seated floating Buna-N O-ring that seals reliably at pressures up to 125 psi. Rated for flows up to 5 gpm with minimal pressure drop.
Designed for Durability and Easy Maintenance
3/4" NPT Threading
Standard inlet and outlet connections fit residential and light commercial plumbing systems without adapters
Buttress Thread Design
Uniform wall thickness and improved threading make cartridge replacement faster and reduce cross-threading risk
Top-Seated O-Ring
Floating Buna-N O-ring creates a leak-proof seal while allowing for thermal expansion and cartridge tolerances
Chemical Resistant
Polypropylene housing and reinforced cap withstand a wide range of water chemistries up to 125°F
Integral Brackets
Built-in mounting points simplify installation without separate bracket hardware (bracket sold separately)
Pressure Relief Button
Improved bleed valve safely depressurizes the housing before cartridge changes

What Works With This Housing
The Pentek 3G housing accepts all standard 10-inch double open end cartridges including sediment, carbon block, pleated polyester, and specialty media filters. Ideal for point-of-entry sediment filtration, well water pretreatment, appliance protection, and single-stage carbon filtration in residential and light commercial settings. The 3/4" NPT threads integrate with standard plumbing and can be adapted to John Guest quick-connect fittings where needed. Commonly paired with Pentek DGD, P5, RFC, R50, and comparable cartridges from other manufacturers.
Pentek 3G housings are manufactured in the USA with materials tested for NSF compliance and long-term reliability in residential water treatment systems.
