Foster Male Dust Plug – Essential accessory for your PCP or HPA setup

This dust plug from Best Fittings is specially designed to keep Foster couplings clean and free from contamination. This accessory fits Foster 12FS, 12FSS and 12MS Straight Thru Quick Snap couplings and prevents dust, dirt or moisture from entering your compressed air system. By sealing the coupling when not in use, you maintain the optimal performance of your PCP air rifle or HPA system.

Technology and application

The dust plug features a male Foster connection that fits seamlessly onto female Foster couplings. The robust metal design with knurled grip makes installation and removal easy, even when wearing gloves. In addition to protection against contamination, you can use this accessory to check the residual pressure in your system. By pressurising the system with the plug installed, you can easily test whether there are any leaks in your air cylinder or filling set.

Ease of use and integration

This accessory comes with a practical red safety cord, so you won’t lose the plug during field use. The plug clicks effortlessly into any Foster coupling and creates an airtight seal. Whether you use a PCP air rifle, an HPA system for airsoft, or a filling set with Foster connections – this dust plug fits any setup where Foster couplings are used.

Who is this accessory for?

This dust plug is ideal for PCP shooters who want to protect their filling hoses and couplings during transport or storage. Airsofters with HPA systems also benefit from this accessory by preventing contamination of their Foster connections. Technicians and maintenance professionals use the plug to test pressure systems without connecting complete filling sets.
