Designed for fluid and pneumatic systems, it reliably prevents reverse flow under temperatures ranging from -30°C to 90°C, making it an essential upgrade for professionals seeking durable, efficient, and chemically resilient valve solutions. ## Description We offer all kinds of check valves for various application, such as ozone-resistant, automotive fuel line systems, water treatment systems etc. We also offer a series of quick couplings, L series, M series, and different piping sizes to give our customers more choices. The flow direction is as shown in the picture. From the white end to the black end. One-way shut off The shell of the one-way check valve is made of ABS material. ABS has very good cold resistance and can be used in cold environments for a long time. In terms of chemical properties, it is resistant to glycerol, inorganic salts, alkalis, polyamino acids, the most alcohols and hydrocarbons; it is resistant to weak acids, but not strong acids, ketones, aldehydes, esters and chlorinated hydrocarbons. The heat resistance is not ideal, the operating temperature is -30-90 ℃ The diaphragm of the one-way check valve is made of silicone rubber, which has excellent high temperature performance and low temperature performance. Silicone rubber is very stable to oxygen, ozone and ultraviolet rays. It performance excellent weather resistance without any additives. Silicone rubber has excellent insulating properties, corona resistance and arc resistance are also very good. We use sophisticated welding machines to ensure that each product is welded and produced qualified ## Features - Diameter ※ 10mm/0.39 inch - Total length ※ 43mm/1.69 inch - Material ※ The shell material is ABS resin, and the Diaphragm material is silicone rubber - Performance※ Normal performance under 25 ℃ to 60 ℃,Strong resistance to acid, alkali, salt corrosion ability - Application ※Check valve is used in fluid system to prevent reverse flow fluid, or used in pneumatic system to prevent reverse flow of compressed air. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B07CC9K599 | | Best Sellers Rank | #27,421 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #38 in Check Valves | | Brand Name | BBTUS | | Connector Type | Barb | | Customer Reviews | 4.4 4.4 out of 5 stars (1,019) 4.4 out of 5 stars | | Exterior Finish | Abs,Rubber | | Included Components | check valve | | Inlet Connection Size | 0.38 Inches | | Inlet Connection Type | Barb | | Item Dimensions | 0.78 x 1.65 x 0.78 inches | | Item Type Name | check valve | | Manufacturer | BBTUS | | Manufacturer Part Number | 99502 | | Material Type | Acrylonitrile Butadiene Styrene (ABS) | | Maximum Pressure | 200 Kilopascal | | Model Number | GY1803 | | Number Of Pieces | 1 | | Number Of Ports | 2 | | Outlet Connection Size | 0.39 Inches | | Outlet Connection Type | Barb | | Set Name | Set of 2 | | Size | 6*4*1cm | | Smart Home Compatibility | Not Smart Home Compatible | | Specification Met | ASTM, NSF | | Thread Size | 0.39 inches | | Thread Type | Barb | | Unit Count | 1.0 Count | | Upc | 191868794092 | | Valve Type | Check Valve | ## Product Details - **Brand:** BBTUS - **Exterior Finish:** Abs,Rubber - **Inlet Connection Size:** 0.38 Inches - **Inlet Connection Type:** Barb - **Item dimensions L x W x H:** 0.78 x 1.65 x 0.78 inches - **Material:** Acrylonitrile Butadiene Styrene (ABS) - **Maximum Operating Pressure:** 200 Kilopascal - **Number of Ports:** 2 - **Outlet Connection Size:** 0.39 Inches - **Outlet Connection Type:** Barb ## Images ![ABS check valve (2PCS) - Image 1](https://m.media-amazon.com/images/I/41Jqv5gM3-L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Used To Repair Cuisinart Coffee Maker *by on Reviewed in the United States January 8, 2026* I used this item to repair my older Cuisinart 12 cup coffee maker. The original check valve which was imbedded in the input water tube had disintegrated and was not available as a replacement part from Cuisinart. I cut out the old valve from the rubber water line tubing and inserted this check valve in its place. The 3/8" nipples fit perfectly into the tubing and sealed well using some small zip ties to tighten. The coffee maker is now working perfectly again. ### ⭐⭐⭐⭐⭐ Worked Very Well as an Air Vent on Discharge Line *by on Reviewed in the United States August 19, 2025* I bought these to install on a dehumidifier condensate line that I had run through a wall to discharge outside of my house. The line was holding water after the pump would stop and I was worried that that line would build up scum or have problems during the colder part of the year. My thinking was this would allow for the entrance of air into the line and breaking the surface tension of the water and allow the line to drain by gravity. This worked exceptionally well for my purpose and fit very easy to install into the 3/8" tubing I had been using. They appear well designed when I checked them in both directions by air pressure. ### ⭐⭐⭐⭐⭐ PERFECT. *by on Reviewed in the United States October 18, 2024* VERY low valve open pressure- perfect for something like a small condensate pump. I recently ran my condensate to a sink drain pipe and wanted some reassurance that if the pipes ever clog I won't have anything flowing back down to my pump. ## Frequently Bought Together - BBTUS 3/8" 10mm Inline vacuum Barbed Check Valve,1Pcs/ 2Pcs /5Pcs ABS One Way Water Non-Return Breather Check Valve for Fuel Gas Liquid Air - Acxico 2Pcs Brake Servo Booster No Return Inline Check Valve Vacuum Hose 10mm 1 Way Check Valve - 3/8 Inch (10mm) ID Fuel Line Hose 10FT NBR Rubber Push Lock Hose High Pressure 300PSI for Automotive Fuel Systems Engines --- ## 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.sg/products/70823648-abs-check-valve-2pcs](https://www.desertcart.sg/products/70823648-abs-check-valve-2pcs) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-03*
