BRASS BODY: The solid brass construction of these shower head adapters offers much higher performance (high heat and pressure resistance) and durability than plastic adapters. This swivel shower head adapter can last for many years without leaking.
LARGE WATER FLOW: The flow rate is 7.8 GPM (@ 60PSI), definitely NO flow restriction! You can enjoy a rain shower experience even if your shower head is 16 inches. RUSTPROOF: Made of brass, the swivel shower head adapter on the shower head extension arm protects against corrosion and rust and requires minimal maintenance. SEAL HAS SWIVEL BALL JOINT: The swivel angle of the ball joint is 23° (11° per side). This swivel ball allows you to adjust the shower head to any angle after installation. The shower angle can be easily adjusted to suit both children and adults. The connection is tight enough so that it will not fall off after being rotated to any angle. Rotate it, and it will stay in exactly the position you need.
