STWROCPB - Streamline Water Maintenance with Sterling ROCP-B CP-Series RO Filter Pack for DWSB-TFC-50 / DWSB-50-PUMP Keep your Sterling under-sink RO performing like new with the OEM ROCP-B filter set. This pack refreshes the pre/post filtration on DWSB-TFC-50 and DWSB-50-PUMP systems— protecting the membrane, improving taste and odor, and restoring flow. It includes the correct sediment, carbon block, granular carbon, and inline post carbon filters; the RO membrane is not included. Most homes service these filters about once per year.

Protect The RO Membrane The PB1005 sediment and GAC10 pre-filters capture grit and chlorine that can foul or damage the TFC membrane, supporting steady production between membrane changes. OEM Parts, No Guesswork This is the Sterling-specified pack for DWSB-TFC-50 and DWSB-50-PUMP; it replaces the exact filter types and sizes your system was designed around. Simple Annual Service Most installations change these filter stages about annually (more often with heavy use or challenging water). Follow the system manual and sanitize the housings during service. Installer-Friendly Format Standard 10? cartridges and an inline post-carbon make swaps straightforward. The inline uses the IC10 series; your system may use IC10Q or IC10T—match what’s installed. STWROTFC50 - Refresh Sterling RO-TFC50 Universal 50 GPD TFC Reverse Osmosis Membrane Restore like-new drinking water performance with the Sterling RO-TFC50 universal RO membrane. This thin-film composite (TFC) element is rated 50 gallons per day, reducing dissolved minerals (TDS) that cause flat taste and scale. Designed for under-sink RO systems, it drops into standard residential membrane housings and pairs with your existing pre/post filters. A great pick for routine maintenance on Sterling DWSB-series systems and many comparable 5-stage ROs. Replace on schedule to keep flow and quality consistent. Brand: Sterling Water Treatment MPN: RO-TFC50 Type: Universal Reverse Osmosis Membrane (TFC) Size/Capacity: 50 GPD (per 24-hour rating) Material/Finish: Thin-Film Composite (spiral-wound element) Performance: Reduces total dissolved solids for improved taste/odor (membrane stage of RO) Connections/Fit: Fits standard residential 1812-style RO membrane housings; compatible with Sterling DWSB-TFC-50 systems Dimensions: Industry-standard 1812 format, approx. 11.75" L × 1.8" Dia (verify your housing) Included: Membrane element (housing, fittings, and filters sold separately) Certifications: Not specified; see system/manual Warranty: See Sterling Water Treatment warranty terms Better Taste With Real TDS Reduction As the heart of your RO system, the TFC membrane is the stage that reduces dissolved minerals (TDS) that cause off-tastes and scaling. Swapping in a fresh RO-TFC50 restores that core performance so ice, coffee, and cooking water taste clean again. Everyday Output For Households Rated 50 gallons per day, this element supports typical under-sink use—drinking, cooking, and a refrigerator line—without over-stressing the system. Keep prefilters current to protect the membrane and maintain consistent production. Universal 1812 Fit, Straightforward Swap Built in the common 1812 size, the membrane is made to slide into standard residential housings used by many brands. That makes maintenance a simple pull-and-replace job with basic hand tools—no special adapters for most installs. Made For Sterling DWSB Systems Sterling specifies a universal 50 GPD membrane for its DWSB-TFC-50 reverse osmosis systems, so this RO-TFC50 is an appropriate replacement when you’re refreshing that platform or similar 5-stage layouts. Protect The Membrane, Extend Service Life For best results, replace sediment and carbon prefilters on schedule—these stages remove particulates and chlorine that can damage a TFC membrane. Many homeowners change the membrane about every 24 months depending on water quality and usage. Sized Right For Tight Under-Sink Spaces At roughly 11.75" long by 1.8" diameter, the element fits compact housings and brackets without crowding shutoffs or supply lines. Always confirm housing size before ordering if you’re uncertain. What’s In The Box This is the membrane element only. Re-use your existing housing and O-rings if they’re in good condition, or replace them during service if worn to prevent leaks.
