MPN: 52-50553
The LONGACRE Durometer with Plastic Case (model 52-50553) is a mechanical analog hardness gauge designed for automotive material testing and diagnostics. This 0–100 point durometer measures the hardness of rubber, elastomers, and polymer compounds—critical data for suspension tuning, tire compound evaluation, and material verification during performance builds. The gauge comes housed in a protective red carrying case, making it portable and field-ready for technicians who need portable hardness testing on the job site or at the track.
The mechanical analog design eliminates dependency on batteries, ensuring reliability in any environment. A full-scale 0–100 point reading range allows precise assessment of elastomer durometers commonly encountered in automotive applications—from soft bushings and dampers to stiffer performance compounds. The compact dimensions (6.95 × 1.65 × 8.35 inches) and light weight (0.51 lbs) enable technicians to carry this tool between workstations without adding bulk to a service kit. Analog needle readout provides immediate visual feedback, with no digital interface to malfunction under shop conditions.
This durometer serves suspension tuners, chassis engineers, and performance shops evaluating rubber compound stiffness during spring and bushing selection. Understanding actual elastomer hardness prevents material mismatches that degrade handling characteristics or accelerate wear. Rubber compound specification sheets provide nominal durometer ratings, but batch variations and environmental aging shift actual hardness—direct measurement confirms you're working with the specified material. The red carrying case protects the gauge from shop impacts and debris while keeping it accessible during development work.
Durometer testing is standard practice across automotive diagnostics, rubber material QA, and OEM component verification. The LONGACRE name carries recognition in motorsports tool circles, where accuracy and durability under repetitive use define tool selection. This mechanical gauge represents a cost-effective baseline for shops transitioning from estimated hardness assessment to quantified material testing.
