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.

This is a barbed coupling used to splice together 3/4" vinyl tubing used in Hot Spring & Tiger River, Limelight, Hot Spot and Solana spas.  This fitting would normally be used in to repair a broken line.

This 3/4" elbow with a 1/4" barbed nipple coming off of the curve of the elbow is most often found on the suction side of the Silentflo 5000 and 5002 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 Wavemaster jet pump. Click on the "More Info" button for details.

3/4" spring clamp (aka wire clamp) is used to secure the 3/4 inch vinyl tubing (70315) to various components.

Note: Wear eye protection when squeezing these little rascals. Service techs typically use either needle nose pliers or hose clamp pliers to squeeze then slide this spring clamp onto the vinyl tubing.
