Inline Flow Control Valve with barb fittings on both ends

Uses an Allen wrench (provided) to adjust flow (keeps unauthorized people from changing flow), also available with lever. Eliminate foam from beer or slow down/ speed up other beverages. Fix systems with issues without having to replace lines or faucets. Take the guess work out of line restriction. You can use shorter lines and still have perfect restriction. You can also use line with larger I.D. Easy to disassemble for cleaning, clear for easy monitoring. Made in Germany from food grade plastic and stainless steel parts!
