Review: Solved My Problem ! - These 1/8” to 1/4” splice connector adapters were the ‘problem solver’ solution I needed to take care of my particular air suspension issue. They met or exceeded OEM quality & fit as described by the manufacturer. The splice connector adapter allowed for a leak free connection between the OEM line and my system fill point. The installation of these splice adapters is pretty straightforward if care is used to ‘straight cut’ & clean connection points & prevent contamination at those points. These splice adapters solved my suspension leak and saved me $$ ! ## Features - 【Product Name】Direct push reducing hose fittings - 【Material】Plastic and stainless steel - 【Size】5/16" (8mm)Tube OD x 1/4" (6.35)Tube OD - 【Maximum Pressure】0~145Psi【Working Temperature】32～140°F - 【Features】Both ends are controlled to connect and disconnect pipes of different sizes,Quick and simple installation,designed for the polyurethane or nylon tubing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09D3M7FSK | | Best Sellers Rank | #3,545 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #11 in Push-to-Connect Fittings | | Brand Name | ROZESAZZ | | Color | 5/16-1/4 zhitongqidongjietou | | Connector Type | Union | | Customer Reviews | 4.6 4.6 out of 5 stars (760) | | Exterior Finish | Stainless Steel | | Included Components | Pneumatic fittings | | Item Weight | 0.01 Ounces | | Manufacturer | rozes | | Material Type | Plastic, Stainless Steel | | Number of Pieces | 10 | | Set Name | Pipe Pneumatic Reducer Set | | Size | 5/16 inch-1/4 inch | | Thread Size | 5/16 inches | | Thread Type | NPT | | UPC | 739642392586 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** ROZESAZZ - **Color:** 5/16-1/4 zhitongqidongjietou - **Connector Type:** Union - **Exterior Finish:** Stainless Steel - **Item Weight:** 0.01 Ounces - **Material:** Plastic, Stainless Steel - **Number of Pieces:** 10 - **Size:** 5/16 inch-1/4 inch - **Thread Size:** 5/16 inches - **Thread Type:** NPT ## Images ![zjxed 5/16" OD x 1/4" OD Pneumatic quick Connector Push to Connect fittings Straight reducer Union/Coupler (Pack of 10) - Image 1](https://m.media-amazon.com/images/I/510aq4FHosL.jpg) ![zjxed 5/16" OD x 1/4" OD Pneumatic quick Connector Push to Connect fittings Straight reducer Union/Coupler (Pack of 10) - Image 2](https://m.media-amazon.com/images/I/41RhGgMQPvL.jpg) ![zjxed 5/16" OD x 1/4" OD Pneumatic quick Connector Push to Connect fittings Straight reducer Union/Coupler (Pack of 10) - Image 3](https://m.media-amazon.com/images/I/51ckI9L4L9L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple push-to-connect fitting that seals right the first time *by C***S on March 16, 2026* zjxed 3/16" OD Push-to-Connect Pneumatic Quick Connector (Straight) These worked exactly as they should.
