Flow & Filtration:
- The Filtered QD Fitting ensures your HPA system receives clean gas, free from particles that could cause leaks or reduce performance.
- The 80-micron filter element captures particles as small as 0.003 inches (the diameter of a human hair), protecting seals and solenoids.
- The conical shape of the filter provides a larger surface area than a disc filter, maintaining optimal flow.
-
Quick Disconnect Compatibility:
- The PolarStar Filtered QD Fitting works with industry-standard Foster 2-Series connectors, which are also used on PolarStar regulators and air lines.
-
Durable Construction:
- The QD Fitting body, machined from corrosion-resistant stainless steel, withstands demanding environments.
-
Easy Installation:
- You can install the fitting easily by pressing it into the standard 6mm Nylon tubing used across all PolarStar HPA systems.
-
Simple Maintenance:
- The filter element cleans and reuses easily. If needed, you can replace it without hassle.
-
Additional Option:
- The PolarStar Filtered QD Fitting is also available for crimped 3/16" ID hose for OEM applications.
Common Product Questions
Find quick answers about our airsoft products, shipping and policies.
Will this part fit my platform?
Compatibility is product-specific. Check the brand, model, size, and platform named in the product description, such as Tokyo Marui Hi-Capa 4.3 or 5.1, AAP-01, Umarex/VFC Glock, or a particular AEG gearbox type.
Similar-looking parts are not always interchangeable, so contact our team with your exact model if you are unsure.
Do I need tools or gunsmithing?
That depends on the upgrade. Simple external parts may be straightforward, but internal upgrades can require disassembly, reassembly, adjustment and testing.
If you are not comfortable working inside your airsoft gun, our team offers professional tech and custom-build services.
Can LA Airsoft install this part for me?
Yes. We can build and upgrade Hi-Capas, AAP platforms, and rifles. Choose your base gun and parts, then add the appropriate tech service.
The current custom-build service states that builds are normally completed in approximately 3 to 5 days, with the team reviewing the selected parts for compatibility.
How should I maintain this product?
Regular maintenance helps preserve performance and reliability. Keep the product clean, follow the manufacturer’s lubrication instructions, and properly manage batteries, gas systems, and internal components. More advanced repairs or internal servicing should be handled by an experienced airsoft technician.
How quickly will my order ship?
Orders without preorder items are typically packed the same day when placed before 4:30 p.m. Central Time. Please note that occasional delays can occur during especially busy periods or when staffing is limited.
Will this part increase my FPS?
Not every upgrade increases FPS. Some parts are designed primarily for reliability, cycling speed, weight reduction, or gas efficiency. When a product has a tested FPS claim, it should be stated in the listing.
