Constructed from reinforced PVC material, it measures 4 inches in diameter and extends 105 feet in length, providing extensive reach for large scale water management tasks. The flexible lay flat design allows the hose to collapse completely when empty, making it easy to roll up for compact storage in garages, sheds, or work vehicles. Its smooth interior lining ensures efficient water flow with minimal friction loss, while the tough outer layer resists abrasion, punctures, weathering, and UV exposure for extended service life. The hose maintains flexibility across a wide temperature range, ensuring year round usability in various climates. A secure stainless steel fastener is included to create a tight, leak resistant connection to your pump or outlet, eliminating the need for extra accessories. Whether draining a swimming pool, managing flood water, transferring liquid waste, or supporting landscaping and farm projects, this hose offers professional grade durability and convenience. Lightweight yet rugged, it is easy to handle, deploy, and reposition by a single user, making it an essential tool for homeowners, contractors, pool service technicians, and property maintenance professionals.
