It has a smooth-running spring and an internal foam strip to keep the blades from rattling and can be installed horizontally or vertically. - ✅ MULTIPLE USE Designed for use in air conditioners, dryers, exhaust, extractor or range hoods, heating ducts, vents, and other HVAC applications. - ✅ EASY INSTALLATION The backflow flap is installed by inserting it into the ventilation pipe until it stops. The position of the spring should be horizontal for horizontal installations so that it can open and close optimally. The backdraft shutter is installed so that the damper blades open only in the outflowing air direction. - ✅ NOTE Back draught valves can be inserted into ventilation ducts which are flexible or non flexible. Cannot be used with plastic ducts as the sizes are different. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | neverest | | Part number | 40545030039031 | | Item Weight | 209 g | | Product Dimensions | 8.8 x 15 x 15 cm; 209 g | | Item model number | 4054503005327 | | Size | 6 Inch | | Color | Silver | | Material | Alloy Steel | | Item Package Quantity | 1 | | Number Of Pieces | 1 | | Batteries Included? | No | | Batteries Required? | No | ## Product Details - **Brand:** neverest - **Color:** Silver - **Connector Type:** Trap - **Exterior Finish:** Galvanised steel - **Item Weight:** 209 Grams - **Item dimensions L x W x H:** 3.46 x 5.91 x 5.91 inches - **Material:** Alloy Steel - **Size:** 6 Inch - **Thread Size:** 6 inch - **Thread Type:** Metric Tapered ## Images ![neverest® RK 150mm Non Return Valve Pipe Fitting Galvanized Steel with Non-Return Valve Automatic Hood Rubber Seal Pipe Connector - Image 1](https://m.media-amazon.com/images/I/61R-zDPpQKL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Funciona perfectamente *by C***N on Reviewed in Spain on 5 April 2024* Hace su función perfectamente. ### ⭐⭐⭐⭐⭐ L'article est très correct *by M***C on Reviewed in France on 20 December 2023* L'article correspond parfaitement à ce que je voulais ### ⭐⭐⭐⭐⭐ Top 👍 *by J***. on Reviewed in Germany on 3 December 2023* Gute Qualität viel besser als die Plastik Teile aus‘m Baumarkt ## Frequently Bought Together - neverest® RK 6" Professional Backdraft Shutter Damper Connector Duct Fits Only with Metal Ducts - EesTeck 4Pcs 6" Adjustable 304 Stainless Steel Duct Clamps Hose Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps（141mm-165mm） - AC Infinity Flexible 6-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust --- ## 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.tn/products/363238687-neverest-rk-150mm-non-return-valve-pipe-fitting-galvanized-steel](https://www.desertcart.tn/products/363238687-neverest-rk-150mm-non-return-valve-pipe-fitting-galvanized-steel) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
