The 2418843 5-inch gun extension is a threaded accessory designed for the Impact 1040 sprayer, available in bulk quantities for contractors, rental fleets, and service centers. This compact extension adds five inches of reach to the spray gun, allowing operators to access tight spaces, reach overhead, or maintain a comfortable distance from overspray without using a ladder.
Constructed from durable materials with precision threads, this extension locks securely between the gun and tip, providing rigid support for accurate spraying. Over time, extensions can become bent from impact, develop thread wear, or have damaged locking mechanisms. A worn extension can lead to wobbly connections, inconsistent spray patterns, or safety hazards. Replacing damaged extensions with this genuine Impact part ensures reliable performance and operator safety.

When replacing gun extensions, inspect these associated components for wear or damage.
Check gun threads for damage; a worn gun can cause poor extension fit.
Ensure tip threads are clean and undamaged for secure connection.
If using a swivel, inspect for smooth rotation and leaks.
