Walker 1.5" Inlet Exhaust Pipe Rain Cap — Heavy-Duty push-on protector for trucks

Walker Heavy Duty 35225 is a 1.5-inch inlet exhaust pipe rain cap that prevents water and debris from entering the tailpipe while fitting a variety of exhaust systems.

This compact rain cap is built for heavy-duty use and designed to slide onto a 1.5" (ID) exhaust pipe for trucks and commercial vehicles. It provides a simple, low-cost barrier against moisture, leaves, and small objects that can collect in the exhaust when a vehicle is parked or exposed to the elements. Walker supplies this accessory as part of a broader range of exhaust repair and maintenance components so you can complete a professional repair using matched parts.

How does this rain cap protect my exhaust when the vehicle sits?

The cap covers the open tailpipe to reduce the amount of rainwater, snow, and debris that can enter and sit in the exhaust system. By keeping contaminants out, it helps limit corrosion and blockages that shorten component life. It’s a passive solution that works continuously without moving parts.

• 1.5" inlet fits many common truck and industrial tailpipes
• Prevents water pooling and foreign object entry
• Durable construction for exposure to weather
• Easy push-on installation — no special tools required

Will this Walker cap work on my vehicle?

The Walker rain cap is designed as a universal accessory but requires a 1.5" internal diameter tailpipe to seat properly. Always measure your exhaust ID and consult any vehicle-specific fitment notes before purchasing. Walker also integrates this cap into its Truck Staxx product line for consistent fit with related parts.

• Confirm inlet ID is 1.5" (internal measurement)
• Check vehicle year/make/model and any fitment notes
• Designed for heavy-duty and truck applications
• Works with Walker Truck Staxx and related systems

How do I install and maintain the Walker 35225 rain cap?

Installation is straightforward: slide the cap onto the exhaust pipe until it seats snugly. No adhesives are required for standard use, though clamps or heat-resistant tape can be added for high-vibration applications. Inspect the cap during routine service and replace if cracked, distorted, or corroded.

• Push-on fit — align and press until secure
• Optional clamp for added retention in heavy-vibration settings
• Inspect at each exhaust service interval
• Replace when damaged to maintain protection

What materials and design features make it heavy duty?

Walker builds this cap from robust materials meant to handle outdoor exposure and the higher temperatures near tailpipes. The shape and wall thickness are chosen to resist deformation while remaining simple to install. It’s sold as part of Walker’s accessory lineup to ensure compatible repairs and long-term performance when paired with their exhaust components.

• Thicker-walled construction for durability
• Shape engineered to shed water and debris
• Made to withstand road and weather exposure
• Packaged as a replacement accessory for complete exhaust jobs

Who is this for: technicians, fleet managers, and vehicle owners who need an affordable, effective way to protect truck or heavy-duty exhaust openings. If you operate commercial vehicles, perform exhaust repairs, or maintain stored equipment, the Walker Heavy Duty 35225 rain cap gives quick protection and pairs with Walker Truck Staxx components for reliable serviceability. Be sure to verify the pipe’s internal diameter and any model-specific fit notes before ordering.
