Underhill h75-100r Ultramax Red Hose 3/4 in 100 Ft 200 Psi

Product Description

The UNDERHILL h75-100r is a 3/4-inch diameter, 100-foot EPDM rubber hose rated for 200 psi working pressure and 800 psi burst pressure. It is built for trade professionals working irrigation, wash-down, and job-site maintenance applications where hose reach, pressure rating, and durability are non-negotiable. The hose body is constructed from EPDM synthetic rubber reinforced with spiral synthetic yarn, giving it resistance to abrasion and kinking under sustained use. The red color provides high visibility on busy job sites. At 100 feet, it covers extended irrigation zones without mid-run connections.

The h75-100r is suited for residential and commercial irrigation installation and service, landscape maintenance, and general wash-down work. The 3/4-inch diameter supports higher flow rates typical of mainline and zone-feed runs. Its kink-resistant construction allows for coiling, dragging, and repositioning across uneven terrain without reducing flow or risking hose failure at the bend. Licensed irrigators, landscape contractors, and general maintenance technicians are the primary installers and users of this hose.

Key Features

• 200 psi working pressure and 800 psi burst rating for high-demand applications
• EPDM synthetic rubber construction resists abrasion, weathering, and UV degradation
• Spiral synthetic yarn reinforcement prevents kinking and maintains hose shape under pressure
• 3/4-inch diameter supports strong flow rates for irrigation and wash-down tasks
• 100-foot length provides extended reach across larger work areas
• Red color improves visibility on active job sites

Compatibility

Designed as a professional-grade replacement or extension hose for 3/4-inch threaded hose fittings used in irrigation, landscape, and general-purpose wash-down systems.

Installation Notes

Shut off the water supply and relieve system pressure before connecting or disconnecting this hose. Ensure all threaded fittings are compatible with 3/4-inch hose thread and are hand-tightened before final snugging with pliers — avoid over-tightening, which can crack fittings. Do not exceed the rated 200 psi working pressure. Store coiled and away from direct heat sources when not in use to extend service life.
