Made from premium CA360/CA377 brass meeting SAE standards, it withstands pressures up to 1200psi and extreme temperatures from -53°C to 121°C. Ideal for professional plumbing and industrial use, this pack of two couplings offers durability, corrosion resistance, and precision fit, ensuring leak-tight connections in demanding environments. ## 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 | | Brand | Legines | | Colour | Copper | | Connector Type | Coupling | | Customer Reviews | 4.6 4.6 out of 5 stars (457) 4.6 out of 5 stars | | Exterior Finish | Brass | | Item Dimensions | 10 x 10 x 10 centimetres | | Manufacturer | Legines | | Material | Brass | | Model Number | 3300*BA | | Number Of Pieces | 2 | | Part Number | 3300*BA | | Size | 1/4" NPT Female x 1/8" NPT Female | | Thread Size | 1/4 | | Thread Type | NPT | | Unit Count | 2.0 count | ## Product Details - **Brand:** Legines - **Colour:** Copper - **Connector type:** Coupling - **Exterior finish:** Brass - **Item dimensions L x W x H:** 10 x 10 x 10 centimetres - **Material:** Brass - **Number of pieces:** 2 - **Size:** 1/4" NPT Female x 1/8" NPT Female - **Thread size:** 1/4 - **Thread type:** NPT ## 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) ![NPT Reducing Coupling Brass 1/4" Female x 1/8" Female, Hex Reducer Coupler Adapter Pipe Fitting 1200psi (Pack of 2) - Image 2](https://m.media-amazon.com/images/I/51mUbVUdPuL.jpg) ![NPT Reducing Coupling Brass 1/4" Female x 1/8" Female, Hex Reducer Coupler Adapter Pipe Fitting 1200psi (Pack of 2) - Image 3](https://m.media-amazon.com/images/I/51GO73jjXgL.jpg) ![NPT Reducing Coupling Brass 1/4" Female x 1/8" Female, Hex Reducer Coupler Adapter Pipe Fitting 1200psi (Pack of 2) - Image 4](https://m.media-amazon.com/images/I/51nN+j2PNkL.jpg) ![NPT Reducing Coupling Brass 1/4" Female x 1/8" Female, Hex Reducer Coupler Adapter Pipe Fitting 1200psi (Pack of 2) - Image 5](https://m.media-amazon.com/images/I/41DG9j4MYzL.jpg) ## Available Options This product comes in different **Size Name** 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.
