Brass Compression Adapters Video
Watch the product video for a closer look at the brass compression male adapter. Use it alongside the product photos and dimension table to review the straight body, compression connection, male threaded end, and space required for installation.
When comparing the adapter with an existing part, check the tube outside diameter and pipe-thread size separately. Also confirm the tubing material, wall thickness, nut and sleeve arrangement, and any part-number suffix. Visual similarity can support identification, but measured dimensions and the approved specification are needed to confirm the correct version.
