Tucker Max-Flow 4" x 40" RO Membrane

What it is

The Tucker 20013-RO-V3 Max-Flow 4" x 40" RO Membrane is an RO membrane for pure-water window and solar panel cleaning systems with 40" housings. It fits the H2Pro, and Tucker's catalog lists the 40" Max-Flow membrane for the Rival V2, the Max Output (which runs two) and the Fill N Go. It is designed to operate at extremely low operating pressures, and Tucker says it produces more water than other 4" x 40" membranes.

Fit and replacement

This is not the replacement membrane for the Tucker 4060, which uses the Max-Flow 4" x 30" RO Membrane. Consider changing it once it removes less than 80% of the impurities in your water: the fewer impurities the RO removes, the more you spend on DI filters.

Install and care

Tucker's manuals say the end nipples may need silicone lubricant to seat in the housing O-rings, with the white O-ring at the top. Never let a membrane dry out: run it at least every two weeks, even off-season. RO membranes are warrantied for factory defect only. The Lubricant Packet (T-Lube) is sold separately.

Free shipping within the lower 48 states. Orders are processed in 1 to 2 business days, and Tucker ships most orders within 2 business days after that from Castle Rock, Colorado, by FedEx Ground, or by LTL freight for items too large for parcel. Production times or low stock can delay an order, and we'll email you if they do. You'll get tracking by email as soon as it leaves the warehouse. For Alaska or Hawaii, contact us before you order.

Inspect the packaging and the product before you sign. Note any damage or shortage on the delivery receipt, then email photos to support@mycleansupplies.com within 48 hours of delivery so the freight claim can be filed. Damage reported after 48 hours can't be claimed.

Unused Tucker equipment in its original packaging can be returned within 21 days of delivery. Ask us for a return authorization before you ship. Returns that aren't due to a defect carry Tucker's 15% restocking fee, you pay the return shipping, the shipping we paid to deliver your order is deducted from the refund, and payment processing fees are not refunded. Opened filters, membranes and resin and special-order items are final sale, and used items and returns damaged in transit back can't be accepted.

Tucker doesn't warrant the Max-Flow 4" x 40" RO Membrane, because filters, RO membranes, DI resin and other filtration components are consumables. Contact us if it arrives damaged or defective.

Warranty claims. Contact us with your order number, model and photos of the fault. We file the claim with Tucker, who may ask for the part back. Approved replacement parts are free; the shipping on them is not, unless the item arrived defective.

Tucker® is the water-fed pole and brush line of Reach Higher Ground (RHG), the Castle Rock, Colorado company that window cleaner Shawn Gavin founded in 2006 to build better pure-water equipment. RHG built its first spot-free system in 2007 and acquired Tucker® in 2015, and today designs, assembles and supports the whole range from its Colorado facility: RO/DI carts and tank systems, carbon fiber and hybrid poles, water-fed brushes and the accessories that tie them together.

The 40" membrane is the longest Max-Flow size; the Max-Flow 4" x 30" RO Membrane runs in the 4060 and the Max-Flow 4" x 21" RO Membrane in the Compact and Skid Mount. RO Preserve protects it during long storage.
