Installation Tips & Tricks

• Power off all equipment and close isolation valves before installation.

• Clean existing threads and inspect the O-ring for wear or debris.

• Apply Teflon tape or thread sealant to the male threads for a proper seal.

• Hand-tighten only, followed by a strap wrench if necessary—do not overtighten to avoid stress cracks.

• Use a Hayward-approved silicone lubricant on O-rings to improve sealing and ease of assembly.

• Once installed, reopen valves slowly and test under pressure to confirm a leak-free connection.
