Due to the joints in rotaries, on rare occasions the joints may dislodge after being moved around, leading to seals being disengaged. On the rare occasion of this occurring, we recommend removing the fitting, pressing in on the joints and rotating them. Then test the fitting for leaking as this will typically fix the issue. We also highly recommend using pressure valves with any rotary fittings. Not responsible for any hardware damage. Use at your own risk. Candy SX finishes can vary in tone based on surfaces. Knurled surfaced appear darker than smooth surfaces!
