Thank you. ### ⭐⭐⭐⭐⭐ Nice check valves *by P***L on February 25, 2021* I bought these to use in line with tubing which goes from the sink soap dispenser pump down into a container of dish soap which sits in the sink cabinet. Without the check valve I could get the tubing primed and it pumped a little but once I stopped using it the soap slowly dropped back down into the soap container. But with the check valve installed the soap stays in the tubing so that whenever I press the soap pump handle I get dish soap dispensed. It removed the difficult task of trying to fill the soap dispenser bottles which were screwed up under the sink. The bottles are no longer under the sink - just tubes running down into the larger dish soap bottle which is very easily replaced. I realize that this was not the original intent for these check valves but they work well for my use which I found from a kind soul who posted a video on YT.. ### ⭐⭐⭐⭐⭐ works as expected *by V***E on December 22, 2023* easy to use seems well made ## Frequently Bought Together - BBTUS 1/8" 3/16" 1/4" 5/16" PA66 Automotive Oil Line Spring Check Valve, Car Fuel Vacuum Check Valve, 2 PCS High Temperature and Corrosion Resistance one-way Oil Pump Check Valve (3/16") - Metaland Brass Hose Barb Reducer, 3/8" to 3/16" Hose ID, Reducing Barbed Hose Splicer Mender Coupler Warter Fuel Air (Pack of 2) - Strongthium 3/16 Fuel Line Hose Set with 10 Pieces Clamps Rubber Gas Tube for ATV Go-carts Mini Bikes 196cc 212cc 6.5hp 5.5hp 8hp 9hp 11hp 13hp Small Engines Generators --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/128185527-automotive-oil-line-spring-and-vacuum-check-valves-pa66-material](https://www.desertcart.vn/products/128185527-automotive-oil-line-spring-and-vacuum-check-valves-pa66-material) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
