The ¼" BSP Male Airline Connector is a 3D printed fitting designed to connect a ¼" BSP female thread to a female quick-release airline coupling. It serves as an extra connector for compressor setups, allowing quick-release air tools or hoses to be attached to standard BSP-threaded compressor outlets.
Material listed for this part is ABS plastic; however, the manufacturer's usage notes specify that the connector was printed and tested in nylon at 160 psi, and has not been tested in PLA or ABS.

Field Ready develops manuals to support both the fabrication and safe use of its products. A maker manual provides step-by-step instructions for replicating the design, including materials, tools, and assembly guidance, so that makers in different locations can build the product accurately and consistently. A user manual, where applicable, explains how to properly set up, use, and maintain the product once it is built, helping ensure it performs safely and as intended for the end user. Together, these manuals make the design accessible to both fabricators and the people who ultimately rely on the product.
