Hauff-Technik HauffRSRT100 Radial Sealing Grommet for 1 Cable 28-50 mm, Core Drill 100 mm, EPDM/Stainless Steel

Forget torque wrenches and complex installation steps—the HauffRSRT100 seals cable entries through simple radial compression. Just insert the cable, position the grommet in the core drilling, and tighten the stainless steel clamping rings. The EPDM body compresses radially around the cable, creating an immediate gas- and watertight seal without any special tools. This makes it a trusted choice for infrastructure and industrial applications where reliability is paramount.

Highlights

• Single cable entry for diameters from 28 mm to 50 mm
• Fits core drillings of 100 mm diameter
• Radial compression sealing principle—no torque wrench required
• Pressure tight up to 2.5 bar (25 m water column)
• Wide operating temperature range: -30 °C to +100 °C
• UV-resistant EPDM grommet with stainless steel clamping rings
• Dry installation for immediate use
• Gas- and watertight seal

In daily use

Installing the HauffRSRT100 is straightforward: insert the cable through the grommet, position it in the core drilling, and tighten the clamping rings to compress the EPDM radially around the cable. The seal is immediate and reliable, preventing ingress of water, gas, and dirt. Its compact dimensions—99 mm outer diameter and 60 mm length—allow it to fit standard wall sleeves and empty pipes. The stainless steel rings resist corrosion, while the EPDM maintains flexibility even at low temperatures, ensuring a durable seal in harsh conditions.
