Iwata HP-M1/M2 Parts

HP-M1 & HP-M2 Parts in This Collection

The HP-M1 and HP-M2 share a similar overall design, but several front-end components are specific to the M3 or M4 configuration. The current collection includes parts for paint delivery, needle control, trigger operation, and gravity-feed cup maintenance.

• Iwata M3 nozzle: Replacement nozzle component for the HP-M1 configuration.
• Iwata M4 nozzle: Replacement nozzle component for the HP-M2 configuration.
• Iwata M3 needle: Model-specific needle used with the corresponding M3 front-end configuration.
• Iwata M4 needle: Model-specific needle used with the corresponding M4 front-end configuration.
• Main lever / trigger: Replacement control component for compatible M-series airbrushes.
• Gravity-feed cup components: Replacement cup lids and related parts for maintaining the paint-cup assembly.

Iwata HP-M1 M3 Needle & Nozzle Parts

The Iwata Revolution HP-M1 uses the M3 configuration shown in this collection. When servicing the front end of the HP-M1, confirm that the replacement needle and nozzle are identified for the M3 setup.

Inspect the needle for bending or visible tip damage and check the nozzle for dried paint, wear, or physical damage before deciding whether replacement is needed.

Iwata HP-M2 M4 Needle & Nozzle Parts

The Iwata Revolution HP-M2 uses the M4 configuration. M4 needles and nozzles should be matched to the HP-M2 rather than selected only by appearance.

Because M3 and M4 components can look similar in product photos, use the airbrush model, product title, and Iwata part number when confirming the correct replacement.

Main Lever & Trigger Component

The current collection also includes an Iwata main lever or trigger component for servicing compatible M-series airbrushes. Trigger parts should be installed in the correct orientation and checked for free movement after reassembly.

If trigger movement changes, inspect the control assembly for dried material, contamination, incorrect positioning, or visible wear before replacing individual components.

Gravity-Feed Cup Lid Replacement Parts

Compatible gravity-feed cup lids are included for maintaining the paint-cup assembly. A cup lid can help cover the paint reservoir during use and can be replaced if the original lid is lost or damaged.

Check the cup size and product compatibility before ordering, since Iwata gravity-feed cup components can vary between models.

How to Choose the Correct HP-M1 or HP-M2 Part

Start with the exact airbrush model and then compare the part name and Iwata part number shown on the individual product page. This is especially important when choosing the needle or nozzle.

• HP-M1: Look for the corresponding M3 needle and nozzle configuration.
• HP-M2: Look for the corresponding M4 needle and nozzle configuration.
• Trigger components: Confirm compatibility with the specific M-series model before installation.
• Cup components: Match the cup or lid size with the airbrush configuration.

HP-M1 & HP-M2 Airbrush Maintenance

Routine cleaning helps reduce dried-paint buildup around the needle, nozzle, gravity-feed cup, and other paint-contact areas. Handle small needle and nozzle components carefully during disassembly and reassembly.

• Flush the paint path after painting sessions.
• Clean the gravity-feed cup and lid after use.
• Remove and clean the needle carefully when needed.
• Inspect the nozzle before assuming replacement is required.
• Check the needle tip for bending or visible damage.
• Confirm M3 or M4 compatibility before replacing front-end parts.
