Stainless Steel Firewall Penetration Kit 1 Inch
FREE Shipping
Overview
|
During the testing phase of our all 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. STC covers the Cessna 140. |

Reviews
Works as advertised. Seems to be a good product and Id recommend it. If you have any doubts on the size, remember that one of the firewall sleeves will get rolled up and go inside the penetration. So opt for the next larger size if you have any doubts.

The penetration appears to be reasonably well made. The rest of the kit is COTS parts. While it certainly does the job for which its intended, Id have to agree with some of the other comments regarding the high cost. That leaves it at 4 stars for me.

I should have read more of the other reviews that mention the kit doesnt include mounting hardware. The item is overpriced for what you get, but convenient so I bought it. Irritating they dont include hardware, so another order to Spruce for SS Cherrymax rivets, wait a week and pay $6.00 shipping. Price and lack of mounting hardware keep it at only four stars.
