The Waterway 400-1940 pump union assembly is designed for compatible pump applications using a 1 inch female buttress thread connection and a 3/4 inch barb tailpiece, and it includes an O-ring. This kind of assembly is useful where a serviceable pump connection must transition directly into flexible tubing instead of rigid hard pipe.
The barb tailpiece makes this Waterway union especially practical in tubing-based systems, while the included O-ring helps produce a more complete replacement at the same time. That can make the repair cleaner and more efficient than sourcing each union component separately.
For compatible pump plumbing systems that use flexible tubing, this Waterway union assembly is a practical option when a 1 inch buttress-thread connection must step into a 3/4 inch barb outlet.
