Phillips Industries has re-designed its poly seal with integrated dust flaps, making it even easier to install with its slightly tapered lip, the company says. When not in use, a trailer’s air system can be contaminated with dust and debris entering through an unprotected gladhand. To replace the need for a shutoff, Phillips Industries worked with a major North American fleet to develop a more economical solution. The grey polyurethane dust flap integrated in the gladhand seal is used with a filter screen creating a barrier which catches dust and debris before it enters the air system. The new grey dust flap seals (12-0167) and filter screens (12-038 and 12-039) are available from an authorized Phillips distributor.
