Safety Bumps™ replace traditional cam and groove caps and plugs, providing a comfortable handle for the driver's hand and a "bump" that extends beyond the hose fittings and ears, protecting them from damage. Safety Bumps™ are available in two, three, and four inch male and female models and in both hazardous and food grade configurations. Safety Bumps™ are made from glass-filled black composite with an anti-static additive. White food grade certified fittings are available on special order, as are blue fittings for non-flammable products. Standard black Safety Bumps™ are biodiesel and ethanol safe.
