Question 1

1. What types of gas hoses and hose assemblies does MilCarb supply?

Accepted Answer

MilCarb supplies gas hoses, tubing, and hose assemblies for a variety of beverage, industrial, and compressed gas applications.Our offerings include fill and vent line kits for BevCarb installations, transfer hoses for bulk gas transfer, braided beverage tubing for CO₂ and nitrogen applications, UV-resistant hose and tubing for outdoor installations, and stainless braided hose for applications requiring higher temperature or pressure capabilities.Standard and custom hose assemblies are available in a variety of lengths and connection configurations. MilCarb can also help identify an appropriate hose or assembly based on the application, pressure requirements, connection type, and installation conditions.

Question 2

2. What is the difference between a fill hose and a vent hose?

Accepted Answer

A fill hose carries liquid CO₂ from the fill box to the bulk tank during a delivery. Because it is part of the liquid fill circuit, the hose must be properly rated for the pressure and service conditions of a bulk CO₂ installation.A vent hose provides a path for CO₂ vapor to be safely routed from the bulk tank to the exterior fill box and vented to atmosphere when required. How the vent circuit is used can vary depending on the design and age of the bulk tank.On older tank designs, the vent circuit may primarily provide an exterior discharge point when tank pressure needs to be relieved. Newer tanks equipped with a Sure-Fill-style circuit can use the vent line during the filling process, allowing vapor to vent as liquid CO₂ enters the tank and reducing the need for the driver to manually blow down pressure during the delivery.Although fill and vent hoses are often installed together, they perform very different functions within the bulk CO₂ system and should be connected to their designated circuits.

Question 3

3. What type of hose should I use for an outdoor CO₂ installation?

Accepted Answer

For outdoor bulk CO₂ tank installations, the gas supply hose should be designed to withstand exposure to sunlight and outdoor conditions. Milcarb offers UV-protected braided hose for this purpose in 1/4", 3/8", and 1/2" inside diameters.Using UV-protected hose helps protect the supply line from deterioration caused by prolonged exposure to sunlight and the elements, helping extend the service life of the hose in outdoor installations.

Question 4

4. Does MilCarb make custom hose assemblies?

Accepted Answer

Yes. MilCarb stocks many of our standard hose assemblies in 5-foot length increments, but custom lengths can be manufactured when a standard size does not meet the installation requirements.Our standard hose assemblies typically use 5/8" female JIC swivel connections, with additional options including 1/2" MNPT swivel or non-swivel connections depending on the application.MilCarb also manufactures hose assemblies for truck-mounted hose reel applications. These assemblies can include a vinyl protective sleeve around the fill-gun connection area to provide additional support for the weight of the fill gun during use.If a standard hose assembly does not fit your application, contact Milcarb with the required length, connection type, and intended use, and we can help determine the appropriate configuration.
