The valve slid easily into the 1/8" tubing I was using and it didn't leak. I used a 25ml syringe with a luer lock to test the check valve. Using water, I was easily able to push it through in one direction, while the other direction completely resisted any flow with no leaks. There is no indicator on the check value for the flow direction, but as you look at it, there is one side that is flared out which I assumed is the side on which the value opens indicating the direction of flow from the flat side to the flared side, and that proved to be correct. So far, these valve have worked flawlessly. I am aware that ethanol can quickly break down seals and tubing that aren't specifically rated for it, but these are being used for some non-critical experimentation. If I find that these check values fail at some point, I will update my review. Review: They're petty good. - Needed low cracking pressure for aquarium dosing pump lines. I was able to fit 2mm ID silicone tube onto the 3 ml barb. Solved my problem of back flow. There is variation between these though. Some have almost no cracking pressure, while others take a bit more. With 4 dosing heads, and this 8 pack, I was able to add two on each line, one before the pump and another after. ## Features - 【Material】 Plastic barb connector, made of high-quality PVED material - 【Size】 1/8" OD One Way Check Valve，Can fit 1/8" hose ID - 【Function】The check valves are applicable for fluid systems to prevent countercurrent liquids, or for pneumatic systems to prevent reverse flow of compressed air. - 【Performance】Hose barb check valve’s Opening pressure: 0.5 Kpa, Maximum back pressure: 300Kpa.

It worked well for this purpose. These are small and have a barb for easy install. Only criticism was it didn't appear one of the valves quickly changed to the open position. But definitely this provides enough flow for my purpose and the price was excellent. ## Frequently Bought Together - ANPTGHT One Way Check Valve 1/8"(3MM) Hose Barb Non Return Ozone Resistance Plastic Valve for Water Fuel Oil Air Gas (Pack of 3) - Metaland 1/8" ID Silicone Tubing, Food Grade 1/8" ID x 3/16" OD 10 Feet Length Pure Silicone Hoses High Temp for Home Brewing Winemaking - ANPTGHT 1/8" Tee Fitting Equal Barb 3 Way Hose Barb Fitting，Splicer Joint Mender Adapter Union Fitting for Fuel Gas Liquid Air (Pack of 5) for Fuel Gas Liquid Air (Pack of 5) --- ## 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.com.pa/products/324620306-anptght-one-way-check-valve](https://www.desertcart.com.pa/products/324620306-anptght-one-way-check-valve) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-07-28*
