Titan 103-625 Rock Catcher Assembly
OEM Titan Filtration Component
Titan 103-625 Rock Catcher Assembly is an OEM filtration component that traps rocks, grit, and aggregate before they enter the fluid system, protecting the pump and internal components on Commander air-powered airless sprayers and compatible Titan equipment [citation:1].
Compatibility Overview
Sits inline to intercept debris before it reaches the pump, valves, and spray tip. Trapping particles early helps prevent damage to critical internal components and reduces the frequency of clogs that interrupt workflow [citation:1]. A cracked housing or degraded seals allow debris through, causing reduced flow, intermittent clogging, and abrasive damage to valves and internal passages.

Titan 103-625 Rock Catcher Assembly for Commander & Compatible Sprayers
Titan 103-625 is an OEM rock catcher assembly designed to trap rocks, grit, and aggregate before they enter the fluid system on Commander air-powered airless sprayers and other compatible Titan equipment. Listed as item "103-625 Rock Catcher" in the official Commander 741-440 owner's manual and the Commander product manual, this filtration component sits inline in the material hose to intercept debris before it reaches the pump, valves, and spray tip. Trapping particles early helps prevent damage to critical internal components and reduces the frequency of clogs that interrupt workflow. The rock catcher is especially valuable in line striping and professional painting applications where operations occur on unpaved surfaces or gravel shoulders, and where aged pavement applications introduce debris contamination risks. Over time, the rock catcher housing can become cracked, seals can degrade, or debris can accumulate to the point where flow is restricted. The rock catcher assembly installs directly into the material hose line and is designed for straightforward service access. Inspect the rock catcher regularly and replace it when the housing shows signs of wear, cracking, or when it no longer seals properly.

The 103-625 Rock Catcher Assembly is a critical filtration component for Commander and compatible spray systems. If you observe reduced material flow, intermittent clogging, or debris downstream in the pump or spray tip, inspect the rock catcher for damage or blockage. Clean the siphon tube and rock catcher after each job, and replace the assembly when the housing shows signs of wear or cracking. Verify model compatibility against your Titan service manual, as filtration configurations vary across sprayer platforms.
