Harder & Steenbeck Infinity CRplus Gravity Feed Airbrush Parts

Parts for Infinity 2007–2023 Airbrushes

Earlier Infinity and Infinity CRplus models belong to a different generation from the redesigned Infinity 2024. Harder & Steenbeck identifies Infinity 2007–2023 as a separate spare-parts platform, making model generation an important consideration when selecting replacement components.

Many service parts can be replaced individually, allowing worn or damaged components to be repaired without replacing the complete airbrush.

Infinity CRplus Nozzle & Needle Configurations

Legacy Infinity CRplus gravity-feed models were available with several FineLine nozzle configurations for different levels of detail, paint delivery, and coverage.

• 0.15 mm setup: Designed for fine-detail and precision-oriented airbrush work.
• 0.2 mm setup: A versatile configuration for detailed painting, gradients, shading, illustration, and modeling.
• 0.4 mm setup: Provides increased paint flow for broader coverage and general-purpose spraying.

Needles, Nozzles & Air Caps

Needles, nozzles, and air caps work together as a matched front-end system. Replacing worn or damaged components can help restore consistent paint delivery and spray control.

• Replacement needles: Match the needle to the compatible nozzle configuration.
• Replacement nozzles: Select the correct size for the corresponding needle and air cap.
• Air caps and crown caps: Maintain proper airflow around the nozzle while providing different levels of needle access and protection.
• Complete headsets: Matched front-end assemblies can simplify replacement or compatible conversion between nozzle configurations.

PTFE Seals, O-Rings & Air Valve Parts

Infinity CRplus models use PTFE sealing components in several areas of the airbrush. Seals, O-rings, and valve parts should be inspected when leaks, inconsistent airflow, or changes in trigger operation occur.

• PTFE needle and nozzle seals: Help maintain proper sealing around the paint system.
• O-rings: Used at compatible cup, air-cap, and internal connection points.
• Valve rods and springs: Support reliable airflow and air-valve return.
• Valve bodies and sockets: Replacement components are available for servicing compatible air-valve assemblies.

Paint Cups & Gravity Feed Components

Infinity CRplus gravity-feed models were available with different paint-cup capacities depending on the configuration. Replacement cups, cup seals, lids, and related components can be used when repairing or configuring the paint-feed system.

Cup compatibility should be checked against the exact Infinity generation because current-generation cups and earlier cup systems are not identical in every configuration.

Quick Fix, Springs & Trigger Control Parts

Infinity airbrushes use rear and internal control components to manage needle movement, trigger response, and paint limitation. Many of these parts can be serviced individually.

• Quick Fix components: Replacement rear parts help maintain the Infinity paint-limiting adjustment system.
• Needle springs: Support consistent needle return during trigger movement.
• Needle guides and clamp parts: Support alignment and secure the needle within the control assembly.
• Trigger and resistance components: Selected parts can restore or adjust the feel of the control system.

Compatible Newer H&S Upgrade Parts

Selected current Harder & Steenbeck components are officially compatible with older Infinity 2007–2023 models. This gives owners additional options when replacing or upgrading selected front-end and control components.

Examples include compatible 0.28 mm and 0.45 mm FineLine headsets, selected needles, nozzles, cups, and trigger components from newer H&S platforms.

Legacy Infinity CRplus vs. Infinity 2024 Parts

The Infinity 2024 CRplus is a redesigned generation with its own titanium 0.25 mm and 0.44 mm headset systems, body components, trigger design, and other model-specific parts.

Some newer components can be fitted to earlier Infinity airbrushes, but this does not mean every Infinity 2024 component is interchangeable with Infinity 2007–2023 models.

Choosing the Correct Infinity CRplus Replacement Part

Confirming the exact airbrush generation and front-end configuration before ordering helps prevent compatibility problems.

• Identify the Infinity generation: Determine whether the airbrush is an Infinity 2007–2023 model or the redesigned Infinity 2024.
• Check the nozzle configuration: Match needles, nozzles, air caps, and related seals correctly.
• Use the manufacturer part number: Part numbers help distinguish visually similar components.
• Verify upgrade compatibility: Only combine components from newer systems when compatibility is specifically confirmed.
