Made from premium CA360/CA377 brass and meeting SAE standards, it withstands pressures up to 1200psi and temperatures from -53°C to 121°C, making it ideal for demanding industrial and plumbing applications. Sold in packs of two, this coupling combines durability, precision, and trusted quality for professional-grade installations. ## Description Legines brass reducing coupling is a brass pipe fitting with female National Pipe Taper (NPT) threads on both ends for connecting male pipes. This reducing coupling has one end that is smaller than the other for connecting different sizes of pipe going in the same direction. It has NPT threads for creating tighter seals than straight threads and is made of brass, which is comparable in strength to stainless steel and is also more corrosion resistant. Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness). ## Features - Reducing Coupling for connecting two different size male threaded pipes - 1/4" Female National Pipe Taper (NPT) threads on one end and 1/8" on another end. - Legines pipe fittings are made of CA360 or CA377 brass, not ordinary copper alloy, and meet SAE standard, have dryseal threads, forgings & extruded. - Operating pressure of our fittings is up to 1200psi, more higher than other general fittings. Temperatures range from -53 to 121 degrees C (-65 to 250 degrees F) - These fittings contain lead and are not allowed by federal law to be installed for potable water use in the U.S.A. and its territories. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07486QJKK | | ASIN | B07486QJKK | | Best Sellers Rank | #126,642 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #937 in Industrial Pipe Fittings | | Brand Name | Legines | | Color | Brass | | Connector Type | Coupling | | Customer Reviews | 4.6 4.6 out of 5 stars (450) | | Customer reviews | 4.6 4.6 out of 5 stars (450) | | Date First Available | 1 February 2018 | | Exterior Finish | Brass | | Is Discontinued By Manufacturer | No | | Item Dimensions | 10 x 10 x 10 centimeters | | Item model number | 3300*BA | | Manufacturer | Legines | | Manufacturer | Legines | | Manufacturer Part Number | 3300*BA | | Material Type | Brass | | Model Number | 3300*BA | | Number of Pieces | 2 | | Product Dimensions | 10 x 10 x 10 cm; 59 g | | Size | 1/4" NPT Female x 1/8" NPT Female | | Thread Size | 0.125 inches | | Thread Type | NPT | | Unit Count | 2.0 Count | ## Product Details - **Brand:** Legines - **Colour:** Brass - **Item dimensions L x W x H:** 10 x 10 x 10 centimeters - **Material:** Brass - **Size:** 1/4" NPT Female x 1/8" NPT Female ## Images ![NPT Reducing Coupling Brass 1/4" Female x 1/8" Female, Hex Reducer Coupler Adapter Pipe Fitting 1200psi (Pack of 2) - Image 1](https://m.media-amazon.com/images/I/51f1UzD80GL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: 1/8 NPT: is this 1/8 x 18 - meaning 18 threats per inch?** A: yes **Q: Can this item be used on a pressure washer with 3100psi ?** A: I would say this fitting would not be appropriate as the description does say it is good for operating pressures of up to 1200psi. There may be a brass version made heavier for use at higher pressure, or perhaps one made of stainless steel instead of brass. I am using it at very low pressure in a computer water cooling loop to adapt thread sizes where a smaller and lighter fitting was preferable for me. I would search for a fitting that states it is good for a 3100psi working pressure or higher, or you are taking a risk of serious injury should this fitting burst. **Q: Which size fits a Schrader valve?** A: A Shrader valve is: 0.305" in OD, thread root diameter 0.302" in x 32 tpi (threads per inch). A Shrader valve is not a NPT thread.
