Iwata High Performance HP-SB Plus Parts

HP-SB Plus Parts in This Collection

The HP-SB Plus combines a side-feed paint system with the internal components used to control airflow, needle movement, and spray delivery. This collection includes replacement parts for several areas of the airbrush.

• Needles and nozzles: H2-compatible fluid components for servicing the front end of the HP-SB Plus.
• Side-feed cups and bottles: Multiple paint-feed options including metal side-feed cups, cup lids, and bottle-based side-feed accessories.
• Air valve components: Air valve, valve body, valve guide, valve set, valve spring, piston, and related parts for maintaining airflow control.
• Trigger and needle-control components: Main lever, needle chucking guide, chucking nut, needle spring, and spring guide.
• Caps, packing, and seals: Needle caps, nozzle caps, crown cap, PTFE needle packing components, and air-valve O-rings.

Iwata HP-SB Plus Needle & Nozzle Components

The needle and nozzle are central to paint delivery and spray control. If spray behavior changes, inspect these components for dried paint, visible damage, bending, or wear before deciding which part needs replacement.

Current replacement options in this collection include an Iwata Needle (H2 and R3), an Iwata Nozzle (H2), an H2 needle cap, H2 nozzle cap, and related front-end components.

Always compare the product title, compatibility details, and Iwata part number with your HP-SB Plus parts diagram before ordering. Similar Iwata components can look alike while being intended for different airbrush configurations.

Side-Feed Cups, Bottles & Paint-Feed Accessories

One of the defining features of the HP-SB Plus is its side-feed configuration. This collection includes several paint-feed components that can be useful when replacing a damaged cup, changing cup capacity, or servicing the side-feed connection.

• Iwata side-feed cups: Metal cup options are available in different capacities for compatible side-feed setups.
• Side-feed cup with lid: A covered cup option for compatible Iwata side-feed airbrush configurations.
• Side-feed bottle: Bottle-based paint-feed components are available for workflows that require a different paint capacity.
• Cup lids and related components: Replacement lids help maintain compatible cup assemblies.

Because several Iwata side-feed cups and accessories may share similar mounting styles, check the individual product listing before ordering for the HP-SB Plus.

Air Valve & Air-Control Replacement Parts

The air-valve assembly controls airflow through the airbrush and works together with the trigger system. If airflow response changes, the valve assembly and its related components are among the areas that may need inspection.

Available components in this collection include the Iwata Air Valve, Air Valve Body, Air Valve Guide, Air Valve Set, Air Valve Spring, Air Valve O-Ring, and Valve Piston.

Inspect small seals and moving parts carefully during service. An airbrush can show similar symptoms from different causes, so identifying the affected component before replacement helps avoid unnecessary part changes.

Trigger, Needle Chucking & Spring Components

Several internal parts work together to translate trigger movement into controlled needle travel. These components can be inspected when trigger movement feels different, the needle does not return normally, or the rear control assembly requires service.

• Main lever / trigger: Replacement lever component for the airbrush control system.
• Needle chucking guide: Helps guide and position the needle within the rear assembly.
• Needle chucking nut: Secures the needle within the chucking mechanism.
• Needle spring: Supports controlled needle return.
• Needle spring guide: Supports alignment and positioning of the rear spring assembly.

Caps, Packing & Sealing Components

Small sealing and protective parts are important when servicing an HP-SB Plus. The collection includes several components used around the needle, nozzle, air valve, and internal fluid path.

• Needle crown cap: Front-end component used around the needle tip.
• Needle cap and nozzle cap: Protect and support compatible front-end assemblies.
• PTFE needle packing screw set: Replacement component for servicing the needle-packing system.
• Air valve O-ring: Replacement seal for compatible air-valve assemblies.
• Blanking cover: Additional component used within compatible side-feed configurations.

How to Choose the Correct HP-SB Plus Part

Before ordering an Iwata HP-SB Plus replacement part, identify the component on the exploded parts diagram and compare it with the product listing.

• Confirm that your airbrush is the High Performance HP-SB Plus.
• Match the Iwata part number whenever one is shown.
• Confirm H2 compatibility when selecting needle, nozzle, or front-end components.
• Check side-feed cup size and connection before ordering cups or lids.
• Inspect related valve parts together when troubleshooting airflow issues.
• Check needle-control parts if trigger or needle movement changes.
• Do not select internal parts based only on appearance.

Maintaining Your Iwata HP-SB Plus

Routine cleaning and inspection can help catch worn or damaged parts before they begin affecting normal airbrush operation. Pay particular attention to the needle, nozzle, side-feed connection, air valve, packing, and trigger components.

• Clean the needle and nozzle after painting sessions.
• Inspect the needle tip before reinstalling it.
• Keep side-feed cup connections and sealing surfaces clean.
• Remove dried paint carefully from front-end components.
• Inspect packing and O-rings when leaks develop.
• Check springs and chucking components if trigger response changes.
• Reassemble small precision parts carefully and without excessive force.
