Talboys flow control devices offer selection and quality. They are finely machined to deliver accurate regulation or interruption of fluid flow. Every flow control device resists corrosion and rust. Hosecocks offer easy one-hand operation. Convex bearing surfaces and rounded edges protect tubing. The adjustment screw has an oversized head for accurate regulation, built-in side lugs for foot mounting, and a tubing retainer screw. (Sample Photo Shown.
