Renusol EPDM Gasket Storm Washer for Hanger Bolts - R900193 Weatherproof Seal for Solar Roof Fixings

Description

The Renusol EPDM Gasket Storm Washer is a weatherproofing washer designed specifically for use with Renusol hanger bolts on pitched roof solar mounting installations. The EPDM (ethylene propylene diene monomer) gasket forms a durable, compressible seal around the hanger bolt penetration, helping keep the roof watertight at every structural fixing point.

As a genuine Renusol component, this storm washer is designed to match the exact bolt diameter used across the Renusol VarioSole and pitched roof mounting range, giving a consistent, reliable seal across the installation.

EPDM Weather Seal

The EPDM rubber gasket is a durable elastomer that resists weathering, UV exposure, and temperature extremes, maintaining a reliable seal over the lifetime of the roof fixing.

Sized for Renusol Hanger Bolts

With an 8.4mm bore and 25mm outer diameter, the gasket is dimensioned specifically to match Renusol hanger bolts, giving a precise, purpose-built fit.

Compression Seal at Each Fixing Point

The gasket compresses around the hanger bolt penetration, sealing against wind-driven rain at every structural fixing point in the mounting system.

Genuine Renusol Component

As an original Renusol part, this washer is engineered to work consistently with the rest of the Renusol pitched roof mounting range.

Straightforward Installation

The washer fits directly onto the hanger bolt during standard bracket installation, adding no extra steps beyond normal mounting procedure.

Supports MCS-Compliant Fixings

Using the correct manufacturer-specified gasket at every hanger bolt penetration helps maintain the weatherproofing standard expected of an MCS certified mounting system.
