for those of you who are getting or currently have a abc fx in your rig, beware of the kidde brand or any other with a plastic head, such as the 10.00 ones. They are ok in some apps but not as much as you would hope.
the plastic heads do not fare to well in a truck that see's alot of sun, the constant heating and cooling of the o-ring and the head will cause them to fail. Then when you need it most, the $10.00 fire ex just failed and you watch a $5000.00 to $15.000 investment burn to the ground.
I sell, service, and deal with everything from 2.5 fx's to 20 lbs, to grease supp, to air plane fire carts all day long, I say I see about 5 to 10 of the cheapy 2.5 lbs fx's that are not charged are do to a plastic head or seal that failed.
your best bet is to get a 2.5 or a 5 lb metal head fx, brands such as ansel are a good name brand.
also any local guys, I can recharge a fx and recertify it for you for free, I get customers all day long that give me there old ones.
