Key Features

• Perfect Compatibility: Designed specifically for Pentair Sand Dollar SD35, Meteor 20", and Sta-Rite Cristal-Flo II 16" systems (2009–present).
• All-In-One Kit: Includes the high-pressure hose, two union nuts, and two 354571 O-rings for a complete "out of the box" repair.
• Built to Last: UV-resistant and chemical-resistant construction ensures longevity under the hot sun and harsh pool environments.
• Standard 1.5" Connection: Features standard union ends for quick, hand-tightened attachment to your equipment.

Technical Specifications

• Part Number: 155709Z (also fits 155709)
• Hose Length: ~25 Inches
• Fitting Size: 1.5-Inch Union
• Application: Above-Ground Filter Systems

🚩 Pro Tip: Don't overtighten the union nuts! Hand-tight is usually sufficient to create a seal with the included O-rings. If you notice a drip, a light coating of silicone-based pool lube on the O-rings works wonders.
