The T238 PTFE Coated Cylinder delivers premium internal performance at a budget-friendly $9 price point, making it one of the most cost-effective airflow upgrades available for AEG builders. Constructed from aircraft-grade 7075-T6 aluminum and finished with a hard-anodized surface (HV ≥ 800), this cylinder provides exceptional rigidity and longevity for mid-range and high-efficiency builds.

Its mirror-polished inner bore and PTFE-infused coating drastically reduce friction, improving piston movement and stabilizing FPS/joule output. Integrated cooling fins promote heat dissipation during sustained firing, helping maintain consistent performance in demanding setups.

Key Features (100% Cylinder Type)

1. High-Strength Materials at an Affordable Price

• Made from 7075-T6 aircraft aluminum
  (Ultimate tensile strength: 572 MPa)

• Hard-anodized (HV ≥ 800) for excellent wear resistance

• Lightweight, strong, and cost-effective—ideal for budget and mid-tier builds

2. Precision-Machined for Optimal Airflow

• Mirror-polished bore eliminates machining marks

• PTFE coating reduces friction to 0.04–0.1

• Enhances air seal stability and reduces piston drag

3. Thermal Optimization

• Integrated cooling fins provide roughly 20% better heat dissipation than smooth-wall cylinders

• Positioning grooves ensure proper alignment with gearboxes that use indexing structures

Important Note:

This is a 100% airflow cylinder with no blowback channel
