Overview
The Kleinn Train Horns brass 4-way air horn manifold, part number K/A54014, is a manifold body with four 1/4-inch FPT ports. FPT stands for female pipe thread, so mating fittings must use the same thread.
The manifold is built to be both attractive and durable. It is universal fit.
Key features
- Brass construction
- Four 1/4-inch FPT ports
- Built to Kleinn quality standards.
- Universal fit
Choosing fittings and lines
The manifold is only as reliable as the fittings threaded into its ports. Since all four ports are female pipe thread, choose male fittings of the same size and check each one before assembly. Mixing thread standards causes leaks that are hard to find once the system is pressurized.
Use the right air line size for the run and support the lines so the manifold is not carrying the weight of long tubing. Apply sealant suited to compressed air to the male threads only, and tighten gradually. After assembly, pressurize the system and check every joint with soapy water.
- Match male fittings to the port thread
- Support long air lines near the manifold
- Check every joint for leaks after assembly
