Tracer Products has introduced the new Tracerline TP-31 Tamper-Evident Straps, which are designed to eliminate the risk of refrigerant cross-contamination in today’s automotive A/C systems and recovery equipment. These straps ensure the purity of the system, while protecting the integrity of the service equipment. Using the straps is a win/win situation for both the vehicle owner and the service technician. For the owner, the straps ensure that the A/C system hasn’t been contaminated with a foreign refrigerant, which can affect system performance and longevity. For the technician, the straps protect his reputation, while guarding against unqualified repairs and costly comebacks. The straps are fast, safe and easy to install. Simply position the strap over the service port, tighten the strap and trim the excess. No special tools are needed to apply the straps and the port is secured from contamination. To complete the installation, just apply the label provided and record the unique serial number found on the strap. The straps come in a convenient zip-lock storage bag complete with 10 tamper- proof tie straps with serial numbers and matching labels.
