Iwata HP-TH2 Airbrush Parts

Iwata HP-TH2 Replacement Parts

The HP-TH2 combines a gravity-feed paint system with a trigger-style control format and interchangeable front-end components. When servicing the airbrush, match each replacement part to the HP-TH2 model and the correct Iwata part number.

• Needles and nozzles: Model-specific front-end components used for paint delivery and spray formation.
• Gravity-feed cups: Compatible cup configurations for different paint-volume needs.
• Fan and round-pattern air caps: Front-end components used with different spray-pattern setups.
• Head and nozzle assemblies: Components that form part of the HP-TH2 front-end system.
• Needle chucking components: Chucking nuts and assemblies that secure and control needle movement.
• Trigger and internal parts: Springs, valve rods, seals, and other service components involved in the airbrush control system.

HP-TH2 Needle, Nozzle & Head Components

The needle and nozzle assembly affects paint flow and spray formation. Damage, dried paint, or wear around these components can change normal airbrush operation.

Before replacing parts, inspect the front assembly carefully and confirm that the needle, nozzle, head, and related components are intended for the HP-TH2 configuration.

• Needle: Inspect the tip for bending, damage, or wear before reinstalling.
• Nozzle: Check the opening and seating area for dried paint, damage, or wear.
• Head assembly: Match replacement head components by model and part number.
• Needle chucking assembly: Confirm correct fitment when servicing the needle-control system.

Fan Pattern & Round Pattern HP-TH2 Air Caps

The HP-TH2 collection includes both fan-pattern and round-pattern air caps, allowing compatible front-end configurations to support different spray shapes and coverage requirements.

Air caps should be selected according to the intended HP-TH2 setup. Confirm the component name and Iwata part number before changing or replacing a spray-pattern component.

HP-TH2 Gravity-Feed Cups & Paint Capacity

Gravity-feed cup options in this collection support different paint volumes and project sizes. Smaller cup configurations can be useful when working with limited amounts of paint, while larger compatible cups provide additional capacity for longer spraying sessions.

Cup size, connection, lid configuration, and HP-TH2 compatibility should all be confirmed before replacing a paint reservoir.

HP-TH2 Trigger, Cam & Needle-Control Parts

The HP-TH2 uses a trigger-style control system with several connected mechanical components. Needle chucking parts, slide-cam components, springs, valve rods, and related pieces should move correctly after cleaning and reassembly.

• Needle chucking nut: Forms part of the system that secures the needle during operation.
• Slide cam spring: Supports movement and return within the trigger-control mechanism.
• Valve rod: Forms part of the internal operating system.
• Preset handle assembly: A model-specific rear component used within the HP-TH2 setup.

HP-TH2 Seals, O-Rings & Internal Components

O-rings and other sealing components are used at specific locations inside the HP-TH2. Wear, contamination, or damage can contribute to leaks or changes in normal operation.

When replacing an O-ring or internal sealing component, confirm the correct part number and installation location rather than selecting the replacement by appearance alone.

How to Choose the Correct Iwata HP-TH2 Part

Start with the exact airbrush model and then compare the component name, Iwata part number, size, and compatibility information shown on the product listing.

• Confirm HP-TH2 compatibility: Make sure the replacement component is listed for the Full Finish HP-TH2.
• Check the Iwata part number: Use the part number whenever possible instead of relying on appearance.
• Match needle and nozzle components: Front-end parts should belong to the correct HP-TH2 setup.
• Identify the air-cap configuration: Confirm whether a fan-pattern or round-pattern component is needed.
• Confirm cup size: Match the gravity-feed cup to the intended paint capacity and connection.
• Review trigger and internal components: Springs, chucking parts, valve rods, and other mechanical parts should be matched to the exact model.

Iwata HP-TH2 Cleaning & Maintenance

Routine cleaning helps reduce dried-paint buildup around the needle, nozzle, gravity-feed cup, air-cap area, paint path, and other moving components. Small internal and front-end parts should be handled carefully during removal and reassembly.

• Flush the paint path after painting sessions.
• Clean the needle carefully before reinstalling it.
• Inspect the nozzle before assuming replacement is required.
• Clean the gravity-feed cup after use.
• Inspect fan and round-pattern air caps for dried paint buildup.
• Check O-rings and seals if leaks appear.
• Inspect trigger and slide-cam components if movement becomes irregular.
• Reassemble internal components in the correct order and orientation.
