Inlet Tubes

Inlet tubes, also called Venturi tubes, are critical components in burner systems and heated assemblies. They are designed to deliver gas, primary air, and mixed gas to the burner assembly for combustion. When creating custom Venturi tubes, working with a reputable and trustworthy manufacturer, such as Stealth Manufacturing, is essential, as production errors can lead to poor combustion, flashback, and other undesirable characteristics.

No matter your industry, Stealth Manufacturing has the expertise, experience, and capabilities to deliver quality results that produce safe and efficient operations.

Custom Venturi Tubes Designed to Your Specs

Stealth Manufacturing makes premium quality inlet tubes from stainless steel and aluminized steel for use with gas burners of a non-tubular design. Along with selecting the best material for your assembly, we will work with you to determine the correct tube diameters as well as making other considerations:

Shutters. Most Venturi tubes have a shutter designed for the precise adjustment of primary air into your burner. They generally locate the orifice for proper concentricity.

Flange vs. Non-Flange. Inlet tubes may be supplied with a flange for convenient bolting onto a mating part. Tubes may also be non-flanged for welding directly to a pan burner or similar unit.
Venturi Feature. Inlet tubes may be constructed with or without a Venturi feature, which is a funnel-shaped element that aids in the mixing of gas and primary air.
