They are 1" FNPT to 3/8" OD. Review: Leaks! - I really wanted to like this product but I had to return it. It seemed well made but the connection to the hose garden hose fitting leaked spraying water everywhere. I verified that there was a washer inside. I tightened it up with wrenches. I tried a new washer. I even tried using plumbers tape but I still leaked. I even tried a different one from the package with the same results. Very disappointing. I have a similar product, 1/4” out instead of 3/8”, and it worked fine. No leaks. desertcart did accept my return. ## Features - Material: Food grade (POM) material, BPA-free, fully used. - Standard: 3/8 inch outer diameter standard connector, suitable for about 9.5 mm water filtration system pipe. - Applicable: 3/4 inch female NPT has a diameter of 24.3 mm, which is suitable for RO water systems and any other joints that use 3/4 inch. - Application: Commonly used in the outlet hose of reverse osmosis (RO) systems such as laundry, gardening, beverage distribution, refrigerators, ice machines, coffee machines, etc. It may not be suitable for GHT garden hose bibs. - Package included: You will get 4 pieces 3/4" to 3/8" quick connect plastic connectors. ## Technical Specifications | Specification | Value | |---------------|-------| | Material | Plastic | | Brand | ZYAMY | | Connector Type | Adapter | | Thread Type | NPT | | Item Weight | 0.05 Kilograms | | Number of Pieces | 4 | | Manufacturer | ZYAMY | | UPC | 728456056890 | | Part Number | SNPTTAWPA-4 | | Item Weight | 1.76 ounces | | Package Dimensions | 4.09 x 2.4 x 1.3 inches | | Item model number | SNPTTAWPA-4 | | Horsepower | 1 hp | | Item Package Quantity | 4 | | Measurement System | metric, inch | | Batteries Included? | No | | Batteries Required? | No | ## Product Details - **Brand:** ZYAMY - **Color:** White - **Connector Type:** Adapter - **Item Weight:** 0.05 Kilograms - **Manufacturer:** ZYAMY - **Material:** Plastic - **Number of Pieces:** 4 - **Set Name:** 1 - **Size:** 3/4 inch - **Thread Type:** NPT ## Images ![ZYAMY 4pcs Straight NPT Thread Adapter 3/4" FNPT to 3/8" Tube OD Push Fit Quick Connect Plastic RO Fittings Water Purifier Accessories - Image 1](https://m.media-amazon.com/images/I/51zg71oVjlL.jpg) ## Customer Reviews ### ⭐⭐⭐ Wrong Size. *by K***R on March 26, 2025* Quality products, but wrong size.
