The Merit Brass X187-40 is a brass pipe fitting designed as a union with female National Pipe Taper (NPT) threads. This fitting enables secure connections for male pipes. The NPT threads on both sides allow for better sealing compared to straight threads and facilitate easier disassembly than couplings. Class 125 indicates a standard for construction and tolerance but is not a direct measurement of pressure capacity.
The Merit Brass X187-40 is ideal for plumbing applications requiring reliable and sturdy connections between pipes.
