Featuring UV inhibitors and a water-resistant formula, it prevents cracking, fading, and friction damage. The innovative Smart Straw allows precise application with two spray options, ensuring easy maintenance of slide-outs, windows, doors, and compartments. Highly rated and trusted by thousands, it’s the essential solution for professional-grade seal care. ## Description Poorly maintained rubber slide-out seals or gaskets can cause deterioration and cracking that allows water, dirt, wind, and even rodents to enter RVs. Contains UV inhibitors which help prevent cracking and fading. Long lasting water resistant formula reduces friction and wear. Extends the life of rubber slid-out and other seals when used regularly. Also works to protect other RV rubber seals including those on windows, doors, compartments and hatches. Great for conditioning rubber seals on RVs, boats, cars, and other vehicles. Safe to use on rubber, metal, vinyl and plastic. Review: Great on house windows too. - I don’t have a RV, I use this on my house windows. It works great. Squeaky hard to open and close windows fixed. Spray on wipe clean and spray again. Do not wipe clean the second time. Review: Lubes great, straw keeps your windows clean - All my RV windows were hard to open. Used this lube on the tracks and now the full-size horizontal window opens smoothly with about a quarter of the effort. The straw nozzle made it easy to reach past the shades to lube the upper track with very little overspray. (I made the mistake of lubing the screen channel as well, and now the screen follows the window every time I open it -- oops!) Our vertical windows saw more limited improvement, but the design of their locks and grips is super poor to start with. This product is a keeper. ## Features - Contains UV inhibitors which help prevent cracking and fading - Long lasting water resistant formula reduces friction and wear - Extends the life of rubber slide-out and other seals when used regularly - Also works to protect other RV rubber seals including those on windows, doors, compartments and hatches - Great for conditioning rubber seals on RVs, boats, cars, and other vehicles ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QL37GPN | | Best Sellers Rank | #902 in Automotive ( See Top 100 in Automotive ) #10 in RV Sealants #2,871 in Oils & Fluids | | Brand | 3-IN-ONE | | Brand Name | 3-IN-ONE | | Container Type | Can | | Customer Reviews | 4.7 out of 5 stars 13,767 Reviews | | Global Trade Identification Number | 10079567120138 | | Included Components | UV Shield | | Item Form | Spray | | Item Type Name | RVcare Rubber Seal Conditioner | | Item Weight | 11 Ounces | | Liquid Volume | 66 Fluid Ounces | | Manufacturer | WD-40 | | Material | Rubber | | Package Information | Can | | Recommended Uses For Product | Automotive, Marine | | Specific Uses For Product | Prevent Corrosion | | Unit Count | 6.0 Count | ## Product Details - **Brand:** 3-IN-ONE - **Item Weight:** 11 Ounces - **Liquid Volume:** 66 Fluid Ounces - **Material:** Rubber - **Package Information:** Can ## Images ![3-IN-ONE Rubber Seal Conditioner - Image 1](https://m.media-amazon.com/images/I/61jGawO71GL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great on house windows too. *by L***. on March 3, 2026* I don’t have a RV, I use this on my house windows.

First time to use a dry lube. Works great and doesn't collect the dust and dirt like oil lube does. ## Frequently Bought Together - 3-IN-ONE RVcare Rubber Seal Conditioner with SMART STRAW SPRAYS 2 WAYS, 11 OZ [6-Pack] - 3-IN-ONE RVcare Window & Track Dry Lube with SMART STRAW SPRAYS 2 WAYS, 10 OZ - WD-40 Specialist Silicone Lubricant with SMART STRAW SPRAYS 2 WAYS, 11 OZ --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/141301580-3-in-one-rubber-seal-conditioner](https://www.desertcart.co.uk/products/141301580-3-in-one-rubber-seal-conditioner) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
