Swing joint adaptors are used to transition from BSP to ACME threads.
It's important to verify the thread type on your sprinkler's inlet—newer, larger sprinklers typically feature ACME threads.
*These adaptors are compatible with all other irrigation brands that use ACME inlets.
If you're replacing a sprinkler installed before 2010, you'll likely need an adaptor to convert from the BSP swing joint to the ACME threaded sprinkler.
