Review: I usually buy the US made fittings but mistakenly bought these instead which are made in PRC. The one of 10 that I’ve used fit well and didn’t have any leaks. I’d have preferred the US made versions, but these definitely get the job done and I didn’t want to hold up progress. Review: Replacing crappy aluminum fittings with these and they work great and the price is a fraction of local suppliers. ## Features - 1/4" female national pipe thread - Maximum inlet pressure of 300 pounds per square inch - 40 standard cubic feet per minute - Maximum temperature of 250 degrees Fahrenheit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000PDUQOW | | Batteries Required? | No | | Batteries included? | No | | Colour | Box of 10 | | Customer Reviews | 4.8 4.8 out of 5 stars (272) | | Date First Available | 4 Aug. 2012 | | Included Components | 1 Milton Branded Product | | Item Package Quantity | 1 | | Item Weight | 45.4 g | | Item model number | 728 | | Manufacturer | Milton Industries | | Material | Alloy Steel | | Measurement System | Inch | | Number of Pieces | 10 | | Part Number | 728 | | Power Source | Air Powered | | Product Dimensions | 0.76 x 0.51 x 1.02 cm; 45.36 g | | Size | Box of 10 | | Special Features | 1/4" female national pipe thread -Maximum inlet pressure of 300 pounds per square inch -40 standard cubic feet per minute -Maximum temperature of 250 degrees Fahrenheit - - - | | Usage | Fleet and plant maintenance. | ## Product Details - **Brand:** Milton - **Colour:** Box of 10 - **Connector type:** Plug - **Exterior finish:** Brass - **Item dimensions L x W x H:** 8 x 5 x 10 millimetres - **Item weight:** 45 g - **Material:** Alloy Steel - **Size:** Box of 10 - **Thread size:** 0.25 inch - **Thread type:** NPT ## Images ![Milton 728 1/4" FNPT M Style Plug - Box of 10 - Image 1](https://m.media-amazon.com/images/I/31AOedWoKJL.jpg) ![Milton 728 1/4" FNPT M Style Plug - Box of 10 - Image 2](https://m.media-amazon.com/images/I/31DR08FVfcL.jpg) ![Milton 728 1/4" FNPT M Style Plug - Box of 10 - Image 3](https://m.media-amazon.com/images/I/31Dbr-3-KfL.jpg) ![Milton 728 1/4" FNPT M Style Plug - Box of 10 - Image 4](https://m.media-amazon.com/images/I/31ZlzTtIEPL.jpg) ![Milton 728 1/4" FNPT M Style Plug - Box of 10 - Image 5](https://m.media-amazon.com/images/I/31lWVhr0F4L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Does this screw on to the valve stem?** A: This is not for a valve stem This is for a air compressor air hose there is a male thread version that usually goes into a air tool **Q: whats the difference between this and 727?** A: The 728 is the Female plug and the 727 is the Male plug that's is difference and they both are 1/4" NPT . **Q: Will these fit craftsman** A: It should fit the Craftsman brand of equipment.
