Iwata HP-TR1 & HP-TR2 Airbrush Parts

HP-TR1 & HP-TR2 Parts in This Collection

The HP-TR series uses a trigger-style control system together with a side-feed paint arrangement. Maintaining these systems may require different replacement components depending on the part being serviced.

• Needles and nozzles: Replacement fluid-system components for maintaining the intended paint delivery and spray setup.
• Needle caps and nozzle caps: Front-end components used around the needle and nozzle assembly.
• Side-feed cup components: Replacement cups, cup lids, and related parts used with compatible TR-series paint-feed configurations.
• Trigger and lever components: Main levers, trigger screws, slide cams, and related parts for servicing the trigger-action mechanism.
• Air-valve components: Air-valve sets, valve rods, O-rings, and related parts used in the airflow-control system.
• Needle-control components: Chucking nuts, chucking guides, needle springs, spring guides, and related internal pieces.
• Packing and internal service parts: Needle packing components, body rings, screws, and other internal replacement parts used during maintenance.

Iwata HP-TR1 & HP-TR2 Needle and Nozzle Parts

The needle and nozzle system plays an important role in paint delivery and spray consistency. If the airbrush begins spraying unevenly, develops paint-flow problems, or has a visibly damaged needle or nozzle, these components should be inspected during troubleshooting.

HP-TR1 and HP-TR2 components are not automatically interchangeable. Check the individual product title, Iwata part number, and listed model compatibility before selecting a replacement needle, nozzle, needle cap, or nozzle cap.

Trigger, Lever & Slide-Cam Components

Unlike a traditional top-button dual-action airbrush, the HP-TR series uses a trigger-style control mechanism. The collection includes replacement parts for this system such as main levers, trigger screws, slide cams, slide-cam springs, needle-control components, and related internal parts.

If the trigger does not move normally or needle response changes, inspect the mechanical parts carefully for buildup, wear, incorrect assembly, or damaged components before replacing parts unnecessarily.

Side-Feed Cups & Paint-Feed Components

Compatible side-feed cup and cup-lid components are included for servicing the paint-feed arrangement of the TR series. Replacement components can be useful when a cup, lid, or related component becomes damaged, worn, or misplaced.

Because different Iwata models can use similar-looking cup components, confirm the part number and compatibility information before ordering.

Air Valve, Seals & Internal Parts

Airflow and mechanical response depend on several small internal components working together. Parts in this collection include air-valve assemblies, valve rods, O-rings, needle packing, springs, body components, and internal guides.

These parts may be useful when servicing symptoms such as changing airflow response, worn seals, unusual trigger movement, or paint reaching areas of the airbrush where it normally should not.

How to Choose the Correct HP-TR Replacement Part

Always identify whether you are servicing an Iwata HP-TR1 or HP-TR2 before ordering. Parts that appear nearly identical may have different specifications or applications.

• Confirm the exact HP-TR model.
• Check the Iwata part number shown in the product listing.
• Match needle and nozzle components to the correct configuration.
• Confirm compatibility for caps and paint-feed components.
• Check trigger, slide-cam, spring, and valve components individually when servicing the control mechanism.

Maintaining Your Iwata HP-TR1 or HP-TR2

Routine cleaning and inspection can help identify problems before more components need attention. Check the fluid path, needle, nozzle, side-feed components, trigger mechanism, and air-valve system whenever airbrush performance changes.

• Clean the needle and nozzle after painting sessions.
• Inspect the needle tip for bending or visible damage.
• Check the nozzle and caps for dried paint buildup.
• Keep the side-feed cup and paint passage clean to support consistent paint delivery.
• Inspect slide-cam and trigger components if control movement changes.
• Check seals and packing components if leaks or internal paint migration occur.
• Reassemble precision components carefully without excessive force.
