Purpose and benefit Practical valve adapter set for pool-service professionals and home enthusiasts who need reliable control over filtration and water routing. Improves filtration efficiency by making it easy to redirect or isolate flow paths and to fine-tune water circulation without complex plumbing changes. Key features Complete white hose adapter set with sealing rings (O-rings) for a secure, leak-resistant connection. Includes control valves and hose clamps to lock fittings in place and prevent leaks during operation. Made from durable ABS for corrosion resistance and long service life in pool environments. Designed to fit 3.8 cm and 3.8 cm filter connections, providing a consistent, tight fit for these standard sizes. How it solves common problems Eliminates guesswork when changing or upgrading hose connections: the included clamps and seals create a reliable seal that reduces downtime and water loss. Gives precise control over water flow so you can balance filtration, heating, and water features without additional valves or tools. Simplifies maintenance and setup, reducing time spent disassembling incompatible fittings or fabricating adapters. Typical applications Public or busy commercial pools: quickly reconfigure flow to different filters or circulation zones during maintenance or peak use. Private backyard pools and above-ground systems: connect or upgrade filter hoses, control flow to heaters or sanitizers, and prevent leaks at hose joints. Seasonal service and repairs: replace worn adapters, add temporary bypasses, or isolate sections of the system for cleaning or inspection. Compatibility and performance notes Intended for use with filter connections measuring 3.8 cm and 3.8 cm. Verify your hose and fitting sizes before installation. ABS construction withstands normal pool chemicals and outdoor exposure; seals and clamps included to ensure a leak-tight installation. What you get: a white ABS hose adapter set with sealing rings, valves, and hose clamps, sized to fit 3.8 cm and 3.8 cm filter connections — a straightforward solution to control and optimize your pool’s filtration and water routing.
