Stainless Steel Firewall Penetration Kit 3/4
Overview
|
During the testing phase of theall stainless steel heater bypass box, we were astounded at the affects of a simulated engine fire on aluminum firewall components. Watching how fast the aluminum melted away (only 16 seconds) took us by surprise. It became very apparent that fireproofing the firewall was more important than most people realize. After many months of trial and error, a fireproof pass through was designed. The firewall Penetration Kits offer a fireproof method of getting wires and cables trough the firewall in a clean, professional looking manner that allows easy removal for replacement if necessary. Testing was initiated on most common methods of wire and cable penetrations available on the market. Simulated engine fire was directed at the stainless shields with rubber grommets, high temperature silicone, eyeball fittings, plain rubber grommets and several untried methods. All failed the fire test with the exception of the steel eyeball, and it only accepts one cable. The kit comes complete with stainless steel fabricated fitting, fire sleeve tubing, two ALL stainless steel hose clamps and a tube of fire block sealant to seal the ends from moisture and gasses. Includes installation instructions.
To determine the size you need, plan where you want to run your wire and cable bundles. Use a tie strap or twist tie to bundle the wires and cables. Measure what size holes the bundle will fit through and choose the NEXT LARGER size (see installation instructions.) You need enough clearance between the bundle and stainless fitting to push the second fire sleeve into the fitting creating the fireproof, chafe proof seal. Typical installation. Wires can be run straight out or turned back to attach on firewall reducing vibration. There are so effective that they received an STC under Advisory Circular AC 20-135 Power plant Installation and Propulsion Systems Component Fire Protection Test Methods, Standards and Criteria. |

Good product. Not heavy. All parts are good quality and instructions are good. Be sure to buy one that is large enough. Measure your bundle then buy the next larger size.

The product is an excellent product and I received it in a timely manner. Thank you.
Stupid expensive for what it is , But it works great
They dont come with the fastener hardware you need to install them, so dont forget to order that too, like I did.
Excellent safety, But make sure you recalculate number of wires you can get through the inner sleeve. It is Much smaller than the 3/4 inch it says.
Catalog shows 2 pictures, one made sense because there were 3 kits of different sizes and reading below it didnt tell you getting only 1 kit. I didnt even see were you chose the size. Overpriced by 3X
