HUINING RO Membrane Housing Kit
The HUINING housing is designed for residential RO membranes with a slim 2.4-inch diameter and 12-inch length. It supports 24GPD through 150GPD membranes, making it versatile for various household needs. Constructed from food-grade PP material, the housing aims to provide durability while keeping weight manageable for easy installation. It features a double-seal design to reduce water bypass and leaks, and a thicker bowl enhances compressive strength to withstand pressure surges typical in home systems.
Membrane Solutions 1812/2012 RO Housing Kit
This housing kit is sized for common RO membranes (1812/2012) and spans 12.5 inches by 2.8 inches. It is compatible with 24GPD to 150GPD configurations and suits many standard brands like APEC, Dow FilmTec, and GE. The kit includes a wrench, quick-connect fittings, check valve, and all essential parts—facilitating straightforward installation with minimal extra tools. A double-seal design minimizes leakage, and a robust end cap plus unibody construction increase resistance to stress and impact.
Hydronix MH03-1812WH Membrane Housing
The Hydronix MH03-1812WH is a 12-inch membrane housing compatible with standard 1/8″ NPT ports. It is NSF certified, which provides independent confirmation of safety and filtration performance. Built with durable polypropylene, this housing emphasizes reliability and straightforward maintenance for typical home RO systems that rely on standard 1812 or 2012 canisters.
Max Water 4040 Membrane Housing
The Max Water 4040 housing is a rugged option built for industrial-scale or heavy-use RO setups. Its 4″ diameter by 40″ length supports larger membrane elements and higher flow rates. The exterior uses corrosion-resistant materials and integrated mounting hardware to handle demanding environments. The kit often includes ends, screws, and assemblies to support a reliable, long-term filtration solution in commercial or larger residential applications.
YKMGON 1812/2012 RO Housing Kit
YKMGON’s kit provides two standard sizes (1812/2012) suitable for membranes from 24GPD to 150GPD. The package includes a wrench, quick-connect fittings, check valve, and tubing, offering a complete installation solution.

HUINING 75GPD RO Membrane Housing Kit
This HUINING kit centers on residential RO needs with a 75GPD membrane and a universal 2.5-inch OD housing suitable for 50–75GPD membranes. It includes multiple quick-connect fittings and a wrench for installation, plus tubing. The design emphasizes effective impurity rejection with a tight seal system to minimize leakage and ensure consistent flow through typical home filtration setups.
MOPUEHEL 600 GPD RO Membrane Housing Set
MOPUEHEL’s 600 GPD assembly targets higher-demand filtration with a standard 12×3 inch membrane size. Made from food-grade materials and BPA-free components, these membranes are designed to deliver high rejection while remaining compatible with typical under-sink RO systems. The set includes a full housing and related components, suitable for maple syrup RO configurations and other high-flow applications where thicker, more robust housings are beneficial.
MOPUEHEL 400 GPD RO Membrane Housing Set
This 400 GPD option from MOPUEHEL offers a balance between high flow and compact size, using a standard 12×3 inch membrane. It is designed for basement or under-sink RO systems and emphasizes safety, non-toxicity, and NSF/ANSI 58 compliance for its membrane components. The housing supports high-performance filtration while remaining compatible with common RO membranes used in residential settings.
Buying Guide: Key Purchase Considerations
- Membrane compatibility: Confirm the housing size (1812/2012, 24-150GPD, or 40″ x 4″ 4040) matches your RO membrane element and your system’s design.
- Seal design and leak resistance: Look for double-seal or enhanced end-cap designs to minimize bypass and drips, especially in tight under-sink spaces.
- Material quality: Food-grade, BPA-free polypropylene housings reduce contamination risk and endure regular contact with treated water.
- Port sizing and fittings: Ensure available fittings (1/8″ NPT, quick-connects) align with your tubing and existing hardware to avoid adapters.
- Installation kit contents: Some kits include wrenches, check valves, and fittings—these reduce the need for extra purchases and simplify setup.
- Maintenance and replacement: Consider how easy it is to replace membranes or seals and whether the kit supports common replacement elements from major brands.
- System scale and intended use: For home use, mid-range 24–100GPD housings fit most households, while larger setups warrant 4040 or 600 GPD housings for higher demand.
- Durability and environmental conditions: Industrial-grade housings (like 4040) are more robust but may require more space and mounting hardware.
- Certification and safety: NSF/ANSI certification for housing components or the membrane itself adds assurance for drinking-water applications.
