Iwata HP-TR2 Airbrush Replacement Parts

HP-TR2 Parts in This Collection

The HP-TR2 uses a trigger-style control system together with a side-feed paint arrangement. The collection includes components for several areas of the airbrush, making it easier to identify the part required for a specific repair or maintenance job.

• Side-feed bottles and cups: Clear and translucent bottle options, side-feed adaptor caps, and compatible paint-cup components for different paint capacities and working setups.
• Needle and nozzle components: Replacement needle, nozzle, needle cap, and nozzle cap parts used in the HP-TR2 fluid system.
• Air-valve components: Air-valve assemblies, valve rods, O-rings, and related airflow-control parts.
• Trigger and lever components: Main lever / trigger parts, trigger screws, slide cams, and slide-cam springs for servicing the HP-TR2 control mechanism.
• Needle-control components: Needle chucking nuts, chucking guides, needle springs, and spring guides for maintaining smooth needle movement.
• Packing and internal parts: Needle packing components, body rings, body-ring screws, handles, and other service parts used inside the airbrush.

Side-Feed Bottles, Cups & Paint-Feed Components

Several HP-TR2 side-feed bottle and cup components are included in this collection. Options shown include clear and translucent bottles with side-feed adaptor caps as well as metal cup components for compatible HP-TR2 setups.

Available paint-feed parts include different capacities, so check the product title and specifications carefully when replacing an existing bottle, adaptor cap, cup, or lid.

Iwata HP-TR2 Needle & Nozzle Components

The collection includes fluid-system parts such as the Iwata R5 nozzle I7041 and Iwata R5 needle I7175, along with compatible front-end components including needle and nozzle caps.

Needle and nozzle condition can affect paint delivery and spray consistency. Inspect these parts when troubleshooting visible needle damage, paint-flow changes, irregular spray patterns, or buildup around the front of the airbrush.

Always compare the replacement part number with your airbrush configuration before installation.

Trigger, Slide Cam & Lever Parts

The HP-TR2 uses a trigger-style control mechanism rather than the traditional top-button layout found on many dual-action airbrushes. Maintaining this system may involve several individual mechanical components.

• Iwata Main Lever / Trigger I7141
• Iwata Main Lever / Trigger Screw I7142
• Iwata Slide Cam I7301
• Iwata Slide Cam Spring I7302
• Iwata Needle Chucking Guide I7152
• Iwata Needle Chucking Nut I1202

If trigger movement changes, inspect these mechanical components for paint buildup, wear, damage, or incorrect assembly before deciding which part requires replacement.

HP-TR2 Air Valve, O-Ring & Internal Components

Airflow response depends on the air-valve system and several small internal components working together. The collection includes parts such as the Iwata Air Valve Set I7121, Valve Rod I7131, and Air Valve O-Ring I1451.

Internal service parts also include needle packing, body components, springs, guides, and related pieces used when maintaining the mechanical operation of the HP-TR2.

How to Choose the Correct HP-TR2 Part

Many airbrush replacement parts are small and can look similar even when they serve different models or assemblies. Before ordering an Iwata HP-TR2 replacement part, identify the component being serviced and compare its part number with the product listing.

• Confirm that your airbrush is the HP-TR2 model.
• Use the parts diagram on this collection page as an identification guide.
• Match the Iwata part number whenever one is provided.
• Check needle, nozzle, and cap compatibility together.
• Confirm bottle, cup, lid, and adaptor compatibility before ordering.
• Check trigger and internal parts individually rather than selecting by appearance alone.

Maintaining Your Iwata HP-TR2

Routine cleaning and inspection can help identify worn or damaged components before they create larger performance problems. Pay particular attention to the fluid system, paint-feed connection, trigger mechanism, and air-valve components.

• Clean the needle and nozzle after painting sessions.
• Remove dried paint from cup, bottle, and adaptor passages.
• Inspect the needle tip before reinstalling it.
• Check O-rings and packing if air or paint leakage develops.
• Inspect slide-cam and trigger components if control movement changes.
• Reassemble small precision components carefully and without excessive force.
