This chrome-plated steel adapter converts a compatible 88 g CO2 connection to a standard paintball-style HPA bottle interface. The product record names the Umarex T4E HDX68/TX68 40 J variant and SIG Sauer MPX, and also describes use with setups that share the matching 88 g thread. The HPA bottle is a separate component.
What the adapter changes
The adapter replaces the 88 g capsule at the connection point and provides the HPA-side interface. It does not replace the need to verify the receiving platform, bottle, regulator, pressure rating and available space as one complete system.
The listed adapter is 4.9 cm long and 2.5 cm in diameter. Those dimensions help check clearance around the connection; they do not establish that every product marketed with an 88 g capsule has enough room or the same surrounding geometry.
Named and conditional compatibility
The current product record directly names HDX68/TX68 40 J and SIG Sauer MPX. Its broader 88 g-thread statement is conditional: the thread, alignment, clearance and approved operating requirements must all match the actual setup.
Keep the HDX68 and TX68 model pair tied to the same model number and caliber. Do not extend the named confirmation to another Umarex T4E model merely because it uses HPA or CO2.

HPA 88g to HPA Adapter UMAREX T4E Series HDX68 TX68 40J Variant SIG Sauer MPX
Why it belongs: The exact adapter converts the named 88 g connection to a paintball-style HPA interface.
Decision boundary: Bottle, regulator, pressure approval and physical clearance remain separate checks.
View the 88 g-to-HPA AdapterSystem checklist before purchase
- Confirm the actual 88 g connection and surrounding clearance.
- Check the bottle and regulator ratings against the marker and adapter requirements.
- Verify the HPA connection type and sealing surfaces.
- Inspect threads, alignment and component condition.
- Use only certified filling equipment and follow every current manufacturer instruction.
A matching thread is only one layer of compatibility. It cannot establish a safe pressure setting or predict a performance result.
Do not confuse interface with output
Changing from a disposable CO2 capsule to regulated HPA can change how the supply is managed, but the adapter alone does not prove consistency, shot count, pressure or Joule values. Those depend on the regulator, bottle, marker condition, temperature and the rest of the system.
Use the quick-piercing guide when comparing the separate two-capsule CO2 route with an HPA conversion.
The buying decision
Choose the adapter when the exact named platform or a verified matching 88 g-thread setup, physical clearance and approved HPA system all align. Do not buy it from the thread description alone when any pressure or space requirement remains unknown.

Why it belongs: This is a related air-supply route for the named T4E families when a remote connection is preferred.
Decision boundary: It is an alternative connection path, not an automatically required part of the dedicated 88 g-to-HPA adapter setup.
