Unions enable the connection of two pieces of 1/4" tubing. Includes inserts. Unions are also available in 3/8 to 3/8 and 1/4 to 3/8. Contact Shoo-fly for any special parts at 352-351-5858
Shoo-Fly is affordable, and saves us money. I would give them 5 out of 5 stars. Truly a well-organized, well-thought-out product that each and every horse owner could be well served by.
