Filter Adapter, 2" female thread (fits MF-170, C-4950)

Filter Adapter, 2" female thread (fits PF-170).

Adapter allows use of the MF-170 Disposable / C-4950 / C-4326, on newer Arctic Spas® (replaces Silver Sentinel - threaded style), and other spas that use a filter with a 2" female thread. 

You only need to purchase the adapter once, and is re-usable with disposable 1 micron filters or pleated style filters.

If you have an older Arctic Spa, that uses a 13-5/16" long filter that is open on both ends (not threaded), then you can use the PF-170 filter without an adapter.
