It is designed for easy installation and allows use with a paintball remote line and CO2 or HPA tanks. The kit reduces reliance on disposable CO2 cartridges while remaining interchangeable with them, delivering longer, more powerful, and more consistent performance between refills.
VaVoger Pneumatic HPA Converters CO2 HPA Kit

This HPA conversion kit by VaVoger offers a remote line adapter for airsoft, BB, and pellet guns. It is designed for straightforward installation to convert an airsoft device for use with a paintball remote line and either CO2 or HPA. It eliminates disposable CO2 cartridges while maintaining compatibility with them, supporting a longer, stronger, and more stable shot rhythm between refills.
SQOTDR 12g CO2 / Pump to PCP Kit

The SQOTDR kit supports converting Crosman 1377/1322/2240/2250/2260 platforms and similar setups. The valve is designed to be sealed under high pressure (up to 800 psi) to prevent leaks, and it is advised to install with the original barrel, grip, trigger set, and probe. The kit aims for a simple upgrade path to PCP-like performance by converting existing hardware with a stable, high-pressure seal.
Ultraforce HPA Converters CO2 HPA Kit

Ultraforce HPA Converters provide an easy installation path to convert compatible guns for use with a paintball remote line, CO2, or HPA tanks. The kit supports S-TW and RG threading and targets delivering longer, more powerful, and consistent shooting across refills, aligning with PCP-style expectations in a CO2-based setup.
LYHgogo PCP 12g Carriers Adapter

This adapter from LYHgogo uses a 12g CO2 cartridge as a quick-change source, enabling easy transitions to 88g or 90g carrier configurations. Constructed from anodized aluminum 6061, the kit emphasizes a lightweight, durable build with a sealed connection to minimize CO2 leakage and maintain efficiency during rapid changes.
Buying Guide
Key purchase considerations for CO2 to PCP conversions include compatibility, thread types, and installation effort. Compatibility ensures your marker, airsoft gun, or PCP device can accept a remote line or adapter without modification. Thread compatibility (such as S-TW or RG) determines whether the kit will fit your existing hardware. Ease of installation matters for field use or DIY setups; look for kits with clear instructions and minimal required tools. Performance expectations should be realistic: while PCP-style consistency can be achieved, the overall result depends on the base platform, regulator stability, and the quality of the remote line.
When comparing options, consider the following perspectives:
- CO2 vs. HPA readiness: Some kits are designed for CO2 only, others support both CO2 and HPA, offering greater flexibility and potentially steadier pressure.
- Maintenance and seals: High-pressure sealing is critical; check for solid seals and components designed to minimize leaks under load.
- Installation complexity: Some kits require removing grips or barrels; others are plug-and-play. Choose based on your comfort with tools and safety.
- Durability and materials: Aluminum or engineered plastics affect weight, heat tolerance, and longevity in field use.
- Cost-to-performance balance: Higher-priced kits may offer more consistent performance, but assess whether the gains align with your intended use and maintenance routine.
Safety note: operate high-pressure systems within recommended limits. Always follow the manufacturer’s instructions for installation, maintenance, and safe handling of compressed gas systems.
