Genexhaust Hardware Only – will fit Firman models with spark arrest cover plate #68 or #88
Please select from the options at the bottom of this page if you would like to order the Genexhaust bolt-on hardware without a hose that will fit Firman models with the spark arrest cover plate #68 or #88. Please scroll through the images to the left and verify that your plate matches one of the two.
The available options are 1" and 1.5” hardware (both for steel or silicone hose), 3/4” NPT hardware, which can be used with 3/4” NPT threaded steel pipe, or 4” hardware, which is used for dryer exhaust type hoses. 4” aluminum exhaust hoses can be purchased at any hardware store.
Scroll through the images to see the available hardware for this model.
The quick disconnect is an extra option and is not included in the price of the hardware alone. You have the option of adding a discounted quick disconnect for 1.5", 3/4" NPT, and 4" hardware, and a discounted through-wall kit for 1" and 1.5" hardware. The prices for each item are listed as you make your selections.
We offer Magnetic Dipsticks that will fit Firman generators that have dipsticks with the following part numbers: P/N 357723513, P/N 330723531, P/N 317723584, and P/N 336723511. If you would like to add a Magnetic Dipstick to your order, you will need to look in your owner’s manual and verify that your generator has a dipstick that matches one of those part numbers. Simply write down the P/N of the dipstick from your generator, and then select the appropriate option when placing your order. We offer Oil Change Tubes that fit Firman generators with dipstick part numbers: P/N 330723531, and P/N 336723511.
Magnetic Dipsticks and Oil Change Tubes are available in two options; anodized and non-anodized. Non-anodized dipsticks are made of aluminum, whereas anodized versions are also aluminum, but go through a coating process that ensures that they will never seize to the aluminum block of the engine. This is especially helpful in marine environments and saltwater environments.
A Through-Wall Kit mounts in the wall of your building or enclosure and allows you to hook up your extension hose and vent your generator exhaust outside. Kits are available in longer and shorter versions for 1" and 1.5” hoses (both for steel or silicone hoses). The longer kit is more suitable for going through thick exterior walls, whereas the shorter kit is more suitable for going through a single layer wall, such as a plastic utility shed.
The longer version of the Through-Wall kit is available in Single or Double Shield. A "Single Shield" kit is one layer of metal, and a "Double Shield" kit has two layers of metal with a space in between each layer, and offers better insulation from the heat of the exhaust. The shorter version of the Through-Wall kit is available in Double Shield only.
Please make a selection in EACH drop down box to ensure order accuracy. Please carefully review your selections before hitting the "Add to Cart" button, as changes cannot be made to your package in the cart.
