Pentek - Standard 20" 3G Filter Housing with 3/4" NPT - Black Cap / Blue Sump - Integrated Bracket with Meter Mount
20" 3G Housing with Integrated Bracket & Meter Mount
Third-generation slim line housing engineered for low-flow residential and light commercial applications. Features 3/4" NPT ports, black polypropylene cap, blue sump, and factory-installed bracket with differential pressure gauge compatibility.
Built for Easy Installation and Long-Term Reliability
Integrated Mounting System
Factory-installed bracket with meter mount eliminates separate hardware purchases. Supports differential pressure gauge installation for real-time filter condition monitoring.
Top-Seated O-Ring Design
Floating Buna-N O-ring provides leak-proof sealing under pressure. Top-seated configuration prevents cartridge bypass and ensures full contact during operation.
Buttress Thread Engineering
Uniform wall thickness and buttress threads make cartridge changes faster and easier. Improved structural integrity handles pressure spikes without deformation.
Low Flow Optimized
Slim line profile with 5.25" diameter fits tight spaces. Rated 2 PSI pressure drop at 5 GPM flow, ideal for point-of-use and single-fixture applications.
Chemical Resistant Construction
Reinforced polypropylene cap and SAN housing withstand chlorine, acids, and caustic solutions. Rated to 125°F for hot water or sanitization cycles.
Accepts All Standard 20" Double Open End Cartridges
This Pentek 3G housing (model 150576) accepts any standard 20-inch DOE cartridge with 2.75" outer diameter. Compatible with sediment, carbon block, pleated polyester, string wound, and specialty media cartridges from Pentek, GE, Culligan, Watts, and DuPont. Inlet and outlet ports are 3/4" female NPT threads. Housing dimensions are 13.375" height x 5.25" diameter.
Cartridge Replacement Schedule
Sediment Pre-Filters
Replace 5-20 micron sediment cartridges quarterly in high-sediment wells or municipal supplies with visible particulate. Inspect pressure gauge monthly.
Carbon Block Filters
Replace activated carbon or carbon block cartridges every 6 months for chlorine taste and odor removal, or when flow rate decreases noticeably.
O-Ring Inspection
Inspect Buna-N O-ring annually during cartridge changes. Replace if cracked, compressed, or showing wear. Lubricate lightly with food-grade silicone.
Pressure Relief Button
Use integrated pressure relief button before cartridge changes to safely depressurize housing. Check button operation quarterly to ensure proper function.
Space-Saving Profile
Slim 5.25" diameter fits under sinks and in tight mechanical spaces where standard housings won't
Pressure Monitoring Ready
Factory meter mount accepts 1/4" pressure gauges for monitoring differential pressure and predicting cartridge life
Tool-Free Cartridge Access
Hand-tighten cap design with improved grip surfaces eliminates need for housing wrenches in most installations
NSF Component Certified
Materials meet NSF standards for drinking water contact when paired with certified filter cartridges
