The RichPen Needle Spring 29708 is listed for the RichPen Apollo 112A 0.2mm gravity-feed airbrush and the RichPen Apollo 112B 0.2mm gravity-feed airbrush.
Confirm both the airbrush model and manufacturer SKU before ordering. Internal springs can look similar while having different lengths, diameters, tension, or fitting requirements.
Part of the Needle Return Assembly
The needle spring is an internal component associated with the needle and trigger mechanism. It helps provide return pressure as the trigger and needle move during normal airbrush operation.
Correct spring tension supports smooth needle return and consistent trigger response. A weakened, damaged, or incorrectly installed spring may affect how the needle returns after the trigger is released.
When the Needle Spring May Need Replacement
- The spring is bent, stretched, compressed, or visibly damaged.
- The needle does not return smoothly after the trigger is released.
- Trigger response feels weak or inconsistent.
- The original spring was lost during maintenance.
- Cleaning and proper adjustment do not restore normal movement.
- The spring no longer seats correctly with the surrounding components.
Product Notice: This listing includes one RichPen Needle Spring 29708 only. The airbrush, needle, needle support, spring screw, trigger components, handle, and other replacement parts are not included.
Compatibility Notice: Compatibility is confirmed for the RichPen Apollo 112A and Apollo 112B. Do not select an internal spring based only on visual similarity.
Installation and Inspection Guidance
- Confirm that the airbrush is a RichPen Apollo 112A or 112B.
- Remove the needle carefully before accessing the spring assembly.
- Work over a clean surface so small internal parts are not lost.
- Inspect the needle support and spring screw for wear or damage.
- Install the spring in the correct position and orientation.
- Do not stretch, bend, cut, or permanently compress the spring.
- Confirm smooth trigger and needle movement after reassembly.
- Test the airbrush with cleaner or water before spraying paint.
Check Related Needle Assembly Components
When replacing the needle spring, inspect the needle support, spring screw, needle, trigger components, and surrounding internal areas. Dried paint, damaged parts, or incorrect adjustment may continue to affect needle return even after a new spring is installed.
Clean reusable components with an airbrush cleaner compatible with the paint being removed. Allow parts to dry before reassembling the airbrush.
