The BOSCH tif555 is a set of three replacement probe tips designed for use with compatible TIF-brand combustible gas leak detectors. These tips serve as the sensing element at the end of the detector probe, making direct contact with the air sample during leak detection work. Worn or damaged tips can reduce detector sensitivity and lead to missed readings, so periodic replacement is standard practice. HVAC technicians and gas service professionals install these tips as part of routine detector maintenance to keep instruments performing accurately.
These replacement tips are suited for residential and light commercial service work where combustible gas leak detection is required. Technicians performing gas line inspections, appliance startup checks, or leak verification after repairs will find this a straightforward consumable replacement to keep on hand. Each package contains three tips, providing multiple replacements from a single purchase.
Compatible with TIF model 5550/A, 5650/A, 5750/A, and H10A combustible gas leak detectors.
Replacement is performed by qualified HVAC technicians or gas service professionals. Power down and turn off the detector before replacing the probe tip. Follow the detector manufacturer's instructions for tip removal and installation to avoid damaging the probe assembly. Allow the detector to complete its warm-up cycle after tip replacement before use.
