PolarStar Air Line Input Fitting – 6mm x 1/8PTC (Threaded)

PolarStar 6mm Air Line Input Fitting – 1/8PTC Threaded Push-to-Connect | HPA QD System Component

The PolarStar Air Line Input Fitting (6mm x 1/8PTC Threaded) serves as a critical connection point within any HPA quick-disconnect (QD) system, ensuring both secure fitment and consistent airflow throughout your setup. Specifically designed for standard 6mm HPA air line tubing, this push-to-connect (PTC) fitting allows for fast installation while simultaneously maintaining a tight, leak-resistant seal. As a result, users benefit from improved reliability and stable air delivery under varying pressure conditions.

Furthermore, this fitting is commonly integrated into QD nipple assemblies used across PolarStar air rigs, making it a highly versatile component for both new builds and system maintenance. Thanks to its ¹/₈ inch threaded interface, it connects seamlessly with standard QD nipples and regulators. Consequently, it offers broad compatibility not only within the PolarStar ecosystem but also across other leading HPA platforms such as Wolverine and Redline systems. In addition, this standardisation simplifies upgrades, replacements, and custom configurations.

Moreover, the compact and durable construction of this fitting ensures long-term performance, even in demanding environments. Whether you are repairing an existing airline or assembling a complete HPA system from scratch, this component delivers consistent and dependable results. However, it is important to note that this fitting requires a Foster-style QD male fitting (sold separately) to complete the connection. Therefore, pairing it with the correct components is essential for achieving a fully functional and efficient air system.

Small but essential, this PolarStar fitting ensures your HPA system runs smoothly with secure, consistent air delivery.
