BSP to ACME Adaptor 1 1/4" to 1 1/4"

This Rain Bird swing-joint adaptor transitions between a 1¼ in BSP connection and a 1¼ in ACME-threaded sprinkler inlet. It is intended for irrigation installations or sprinkler replacements where the existing swing joint and selected rotor use different thread forms.

Connection sizes

• BSP side: 1¼ in
• ACME side: 1¼ in
• Supplier SKU: RBSJA-ADPT125

BSP and ACME threads are different and must not be forced together. Check the swing-joint outlet, sprinkler inlet, thread size and thread form before ordering. Follow the sprinkler and swing-joint manufacturers’ sealing and installation guidance, then pressure-test the completed joint.
