Product Description

This 40mm White PVC Flexi Water Hose is a spa‑grade flexible hose designed for water circulation, suction lines, and return plumbing in spas and pools. Its rib‑reinforced structure provides excellent flexibility, allowing it to route around tight corners and confined spaces—making it ideal for spa retrofits and new installations.

According to Terraflex, spa‑grade flexible PVC hoses use a rigid PVC helix reinforcement, providing durability against pressure, impacts, and compression while remaining highly flexible for installation in spa and pool systems.

Manufacturer specifications for SPA FLEX hoses confirm that flexible PVC hoses are designed specifically for Jacuzzi, whirlpools, jetted tubs, and pool systems, providing a rugged but bendable alternative to rigid PVC pipe. These hoses are compatible with standard Schedule 40 PVC fittings, simplifying repairs and upgrades.
