If you have an older rubber hose through with which you apply hot asphalt tar onto driveway surfaces, you may wonder if it may be getting too old and worn for safe usage. If so, look for the following signs that your equipment's hot tar hose should be replaced.
You Can See Small Leaks
One sign that your tar hose needs replacing is the presence of small leaks. Even if the tar is only dribbling out of tiny holes in the hose's rubber, these holes are often a precursor to more severe damage in the near future.
Small holes in the rubber of a tar hose mean that the integrity of the material has been compromised. Since this type of hose is meant to be heat resistant to accommodate the high temperatures of the tar, the coating that serves this purpose is no longer intact.
Once there are one or more tears in the coating, the heat is able to penetrate the underlying rubber, causing rapid deterioration of the rubber. Since the rubber has started to deteriorate, the hose is no longer able to tolerate both the heat and pressure of the hot tar as it flows through the hose.
If you use a hose in this condition, you run the risk of having the rubber rupture while you or one of your workers are using it. Then, hot tar would spew out from the ruptured area uncontrollably, possibly damaging nearby property or seriously burning anyone with which it comes into contact.
Fittings Are Corroded
Along with small leaks in the hose, other places at which you should look when deciding whether or not to replace a tar hose are the fittings. If the fittings are corroded, you will need to replace the entire hose.
Once the fittings become corroded, they will no longer be able to hold together the areas of attachment with other hoses or your equipment. If the fittings break loose during use, the pressurized tar could cause serious damage.
Also, since tar hoses are often reinforced with metal, the corrosion you can see on the fittings could have spread inside the rubber. This corrosion would then jeopardize the infrastructure of the hose and make it unsafe to use.
If you discover that your rubber tar hose has one or both of the above signs of damage, replace it as soon as you can to avoid possible property damage and injuries. Contact companies like Copperstate Hose to select a hot tar hose that best suits your needs.
