Vinyl Tubing, Thick Walled, 3/4" Dia. (ID) x 36"

This coupling is most often found on the discharge side of the Laing 303 and Calvert (Cal-200) circulating pumps. The 3/4" x 3/4" x 1/4" bleed line fitting has a 1/4" nipple (30598) for the 1/4" vinyl tubing that's coming from the front of the jet pump to secure to. The purpose of the 1/4" tube is to draw air out of the circ pump and heater so they can quickly fill with water and prime. This is achieved by immediately activating the jet pump once the spa is powered up after the refill. The 1/4" line also helps the equipment drain out better when the spa is drained.
