PREMA PRE-PB-5 Bias Ply Tire Repair Unit, 4.75" Diameter, 4-Ply, Box of 10

Q: What's the difference between PB-5 and PB-5-HC patches? A: PB-5 patches use cold chemical vulcanization with PREMA Ultra Fast Dry cement for room temperature curing within 2-4 hours typically. PB-5-HC requires heat vulcanization equipment with PREMABOND HC cement and won't cure chemically, making PB-5 ideal for shops without heat-cure equipment.

Q: Can these patches be used on radial tires? A: No, PB-5 patches are specifically engineered for bias-ply tire construction with fabric reinforcement layers.
