Generator exhausts all have one of two options; either a welded on exhaust flange or a bolt on flange. As such, we offer exhaust extensions to accommodate either type.
To determine what you will need, you will first need to look at your generator and determine which kind of exhaust your unit has. If your unit is not listed in the model specific designs below, you will also need to measure the length and diameter of your generator exhaust flange.
In addition to exhaust extensions, we also offer quick disconnects, magnetic dipsticks, oil change tubes, and through wall kits which can be purchased individually, or are offered at a discount when purchased with your exhaust extension. Please scroll down through this entire page to see the details on these additional options.
Exhaust extensions are available in two types of tubing options:
We offer both steel and silicone extension hoses. They both work great, yet certain applications may be more appropriate for one over the other. For example, marine and saltwater environments may be better suited for silicone hoses, or applications which would require frequently moving and bending the hose may be better suited for silicone.
Steel hoses, while also flexible, may be more appropriate for applications where the hose will not be moved as frequently. Steel hoses also offer more durability in a situation where the hose may be bumped into as it wouldn’t be subject to tears that could occur in silicone hoses if the hose was bumped up against another object. For example, if a hose will be carried around daily in the back of a work truck, then a steel hose would probably be more appropriate for that situation.
Steel Extension Hose
1” or 1-1/2” ID galvanized flexible steel tubing: Tubing is able to make a 4-5” radius bend (1” ID) or 6-7” radius (1-1/2” ID). The tubing will get hot and lose some flexibility after a few cycles. If running tubing through a flammable material, header wrap is recommended. This tubing is a standard automotive grade that forms and stays easily.
Silicone Extension Hose
¾”, 1″, or 1-1/2” ID silicone lined tubing: Tubing is very flexible and can make tight bends while the internal bronze coated wire coil prevents collapsing. This tubing will remain flexible after repeated heat cycles. Although this tubing does not get as hot as the steel tubing, the surface of the tubing will be hot to the touch and if running the tubing through a flammable material, header wrap is recommended. This tubing is a standard aviation grade tubing that can withstand temperatures from -80 to +550°F.
BOLT ON EXHAUST EXTENSION KITS
Bolt on extension kits are available for the following models, and will accommodate universal generators with matching sizes. Hoses are available in 3 ft, 5 ft, and 8 ft lengths. Custom lengths are also available by request.
Champion 3500/3400/3100/2800 watt inverter & universal generators. The flange is 1/8” stainless with ¼” wide slots that will accept from 1.46” to 2.00” center to center mounting bolt spacing.
Honda EU3000is inverter generators. The flange is 1/8” stainless with ¼” wide slots that will accept from 1.70” X 2.00” center to center mounting bolt spacing. Included is a gasket designed for the EU3000is along with all other required mounting hardware.
Honda EU6500is or EU7000is inverter generators. The flange is 1/8” stainless with ¼” wide slots that will accept from 1.70” X 2.00” center to center mounting bolt spacing. Included is a gasket designed for the EU6500 or EU7000is along with all other required mounting hardware.
WELD ON EXHAUST EXTENSION KITS
Weld-on extension kits are for makes and models that do not have a bolted flange. Several variations are offered to suit specific needs. Hoses are available in 3 ft, 5 ft, and 8 ft lengths. Custom lengths are also available by request.
Weld-on extensions will need to have the tip of the extension welded over the exhaust flange. The extension hose will still be able to be removed, either with a quick disconnect, or by unthreading the hose from the tip.
Make/model specific weld-on designs:
- Champion 2000W inverter
- Generac iX2000
- Generac XG6500E/XG7000E/XG8000E
- Honda EU1000i
- Honda EU2000i
- Yamaha EF1000iS/EF2000iS/EF2400iSHC
Universal weld-on designs:
- Up to Ø11/16” (17.5mm) X 3/4” (19mm) long exhaust port with either no weld bead or weld bead under Ø27/32” (21mm) – same as Generac iX2000
- Up to Ø15/16” (24mm) X 1” (25-1/2mm) long exhaust port with either no weld bead or weld bead under Ø1.0” (25-1/2mm) – same as Generac XG6500E/XG7000E/XG8000E
- Up to Ø15/16” (24mm) X 1” (25-1/2) long exhaust port with no weld bead or weld bead under Ø1-3/8” (35mm)
- Up to Ø1-1/4” (32mm) X 1-1/2” (38mm) long exhaust port with either no weld bead or weld bead under Ø1-7/16” (36.5mm)
Optional Quick Disconnect Fittings
Through-Wall Exhaust Ports
Quick disconnect fittings allow you to quickly remove your hose from your generator, and are available on the 1-1/2” tubing designs. Fittings are open, so generator can be run with remaining half of fitting without issue. These fittings are fitted with a high temperature O-ring seal for durability. If a quick disconnect is being considered, it can always be added to any 1-1/2” tubing design at a later date.
Through-wall exhaust ports for 1” and 1-1/2” ID tubing are available to complete your project. These kits are constructed from stainless steel to give you years of trouble free service. The overall length of the assembly is approximately 13” with about 8” of that going through the wall. Inside wall mounting brackets and the proper clamp are included in the kit. Both single and double wall designs are available.
Along with exhaust extensions, top of the line magnetic dipsticks and oil change tubes are offered for some makes and models. During normal operation of a generator, fine metal shavings will develop in the oil thus causing significant engine wear. Our highly magnetic dipsticks are very effective at collecting these metal shavings; thus greatly reducing wear and tear on the engine.
Magnetic dipsticks are interchangeable that fit the EU1000i, EU2000i, and EU3000is, along with Honda engine models GX100, and GXH50.
A different design magnetic dipstick is available that fits the EU6500is, EU7000is, along with Honda engine models GX240, GX270, GX340, and GX390.
Magnetic dipsticks are available to fit the Champion 3500/3400/3100/2800 watt inverter generators. A similar design, but specific to the Champion 2000 watt inverter generator is also available.
Magnetic dipsticks are available in two options; anodized and non-anodized. Non-anodized tubes are made of aluminum, whereas anodized tubes are also aluminum, but go through a coating process that ensures that the aluminum dipstick will never seize to the aluminum block of the engine. This is especially helpful in marine and saltwater environments. The anodized dipsticks appear to be maroon in color.
OIL CHANGE TUBES
Our oil change tubes are premium quality and make changing the oil on your Honda EU1000i or EU2000i generator easy, allowing you to tip and drain your unit without causing a messy oil spill. Our oil change tube will fit both a Honda EU1000i and EU2000i model generator.
Oil Change Tubes are also available in two options; anodized and non-anodized. Non-anodized tubes are made of aluminum, whereas anodized tubes are also aluminum, but go through a coating process that ensures that the aluminum dipstick will never seize to the aluminum block of the engine. This is especially helpful in marine environments and saltwater environments.. The anodized oil change tubes appear to be maroon in color.
