Edstrom Vari-Flo Valve with Stainless Steel Stem guard, 3/16"barb

Price: $7.75
Item Number: 1000-1451-GP
This valve is designed for guinea pigs. It features a play guard that prevents GPs from wasting water. This guard is stainless steel. This model has 3/16" barb connection for use with Flex-Tube plumbing systems.

How it Works: To drink, animals simply move the stainless steel stem by biting or licking, releasing water. When the animal releases the end of the stem, the elasticity of the silicone rubber diaphragm located behind the stem head pushes the head back to the closed position, stopping the flow of water.
