  • Gauge Cage for Taprite Regulator

    Gauge Cage | For Taprite Regulator | Mounting Bolt & Washer Included

    23 reviews

    Protect your regulator from damage in the event your tank gets knocked over. A Gauge Cage is cheap insurance that can help save you a costly regulator replacement. Mounting bolt and washer included. CO2 and Nitrogen tanks, especially the 5lb size most brewers use, are notoriously wobbly and easy to knock over once the regulator is mounted on them. This handy Gauge Cage helps protect the gauges themselves, as well as the fragile points where they thread into the regulator body, from damage in case of a fall.   Specifically sized to fit our D1060 and D1070 Taprite brand ragulators, these cages may not fit some budget regulators manufactured overseas.

  • Inline Flow Control Compensator

    CMBecker In-Line Flow Control Compensator

    14 reviews

    Add the perfect amount of restriction to any beer line to reduce foam. Eliminates the need for flow control in the faucet itself. Great for use in Jockey Boxes or anywhere you are serving beverages with varying levels of carbonation.    If you are currently using a long length of tubing to increase restriction you can now shorten your tubing. A shorter line holds less beer. Beer that is stored in the line tends to warm up quicker, adding to foaming issues, and is more likely to stale from bacteria present in the line.    Features: Adjust flow with an included Allen wrench (keeps unauthorized people from adjusting the unit) Eliminate foam from beer or slow down / speed up other beverages Fix systems with issues without having to replace lines or faucets Take the guesswork out of line restriction.  You can use shorter lines and still have perfect restriction.  You can also use larger ID lines and adjust as necessary. Easy to disassemble for cleaning, clear body for easy monitoring Made in Germany by CM Becker from Food grade plastic and stainless steel parts! Comes Equipped with 2 x 3/16" Barbs Easy to install to any existing beer line (cut line and install two clamps)
