Water Filter & RO
Drinking Water Faucets

A water filter faucet is designed for standard under-sink filtration systems — carbon block, sediment, or multi-stage filters — that connect to the existing cold water supply line. An RO faucet is a dedicated dispensing faucet for reverse osmosis systems, which produce purified water slowly and store it in a pressurized tank.

RO faucets have a separate supply line from the RO storage tank and are not connected to the main water supply. The two product types are not interchangeable — an RO system requires an RO faucet, while a standard filter system uses a filter faucet.

It depends on the installation market. Air gap faucets are required by plumbing code in several US states — California, Massachusetts, and others — and are increasingly specified in commercial projects. Non-air gap faucets are permitted in most US states and are the standard choice for residential RO system OEMs because they're simpler to install.

If you're distributing across multiple US states, carrying both configurations is the safest approach. We manufacture both variants with identical body castings and matched finishes, so they can be sold as a coordinated product line.

cUPC certification covers plumbing code compliance for most US states and Canadian provinces. NSF/ANSI 61 Section 9 is the drinking water contact material standard — some states (California, Vermont, Maryland, and others) have adopted it into law, and many retailers and distributors require it as a condition of listing.

We hold cUPC and can provide NSF 61 material documentation. If your buyers require a full NSF 61 product certification (as opposed to material compliance documentation), we can discuss the certification extension process for specific SKUs.

200 pieces per SKU for OEM orders with custom tooling. For ODM orders starting from our existing catalog bodies with modified finishes or branding, the MOQ is the same.

Most new buyers start with a 200-unit trial order in one or two variants to test market response before scaling to container quantities.

Three layers: material specification, incoming inspection, and surface treatment.

XRF test reports and material certifications available with each shipment.

In most cases, yes. Send us a physical sample of your existing faucet and we'll do a side-by-side comparison against our standard plating outputs. For brushed finishes, the brush direction and grit profile matter as much as the base metal color — we can adjust both.

For matte black and ORB (oil-rubbed bronze), we match by PVD or electrocoating parameters. Exact visual match depends on the substrate and process your current supplier uses, so we always recommend a pre-production sample approval step before committing to a full run.

Lead time depends on whether you're ordering from existing tooling or requiring new tooling development.

Add 2–4 weeks for ocean freight to US West Coast ports. Chinese New Year and Golden Week holidays affect scheduling — plan orders accordingly.

Yes. Our filter faucets use a standard 1/4" compression inlet fitting, which is the universal connection for under-sink carbon block, multi-stage, and RO systems sold in North America and Europe. The faucet body accepts standard 3/8" sink deck hole mounting.

For RO systems specifically, the non-air-gap models connect directly to the RO storage tank line. Air-gap models have a three-port body — supply in, drain out, and filtered water up — and require a drain saddle connection during installation. Both configurations are fully documented in our installation guides, which we can white-label for your brand.
