Reducing Unions are stainless steel fittings used to connect two tubes or pipes of different diameters while maintaining a secure, leak-tight union connection. The union design allows the fitting to be assembled and disassembled without cutting the tubing, making it ideal for maintenance or system modifications.
Common Thread Types:
a. NPT Thread: Thread interference (uses PTFE sealant/tape)
b. BSPP Thread: Uses O-ring or bonded washer
c. BSPT Thread: Thread interference (similar to NPT)
d. JIC 37° Flare: 37° metal-to-metal flare seal
