Replacement Pool Hose Adapter A with Collar Function Converts a 3.8 cm (outer) pool hose to a 3.2 cm hose to fit pumps with smaller threaded inlets. Designed as a direct replacement adapter A for threaded pump connections. Key benefits — why you need it Creates a secure, leak-resistant connection: the collar compresses the hose for a tighter seal and fewer leaks during operation. Prevents hose slip: collar design keeps hoses in place under pressure, reducing disconnections and downtime. Saves time and cost: reuse existing hoses and avoid replacing whole lengths of hose or buying new pump fittings. Tool-free installation: medium-size collar allows hand-tight installation for quick setup and seasonal changes. Compatibility and size Fits standard threaded connection pumps commonly used in pool systems. Designed to adapt 3.8 cm hose to 3.2 cm inlet; medium-size collar for easy handling. Intended for typical pool hose diameters and pump thread styles; use with pumps that accept threaded adapters. Material and performance Built for regular pool use with durable construction to withstand routine pressure and handling. Provides a reliable connection under normal pump operating conditions. Installation and maintenance Hand-tighten the collar for a secure fit; no special tools required. Inspect periodically for wear, cracking, or loosening and replace if damaged to maintain a leak-free connection. Practical use scenarios Replace a worn or incompatible adapter on a pool pump while keeping your existing hoses. Connect a 3.8 cm hose to a pump with a 3.2 cm inlet when using a different pump or accessory. Quickly swap or adapt hoses during seasonal setup when multiple hose sizes and pumps are in use.
