Description
The Deublin 6827K42 is a single-passage, one-way-flow rotary union (swivel joint) engineered to deliver a dependable, leak-free connection between stationary supply lines and rotating equipment. Constructed with an aluminum body and featuring a 1/4″ port size, this compact union is well suited for HVAC, industrial, and mechanical systems where continuous media transfer through a rotating interface is required.
