Filter Adapter, 2" female thread (for PF-170), by PuraSpa
Filter Adapter, 2" female thread (fits PF-170 or C-4326, C-4950). Made by PuraSpa®.
Adapter allows use of the PuraSpa PF-170 disposable filter 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.
