Pipe clamp SpiroFlex SpiroFlex 125 with rubber damper OA125-OC, 125 mm

SpiroFlex 125 pipe clamp OA125-OC is a mounting clamp designed for 125 mm diameter round ducts and pipes with an integrated rubber damper that reduces vibration transmission and noise. The clamp secures HVAC ducts, ventilation pipes and other round conduits to walls, ceilings or mounting brackets while providing elastic isolation between the metal clamp body and the supported element. The construction is intended for installations where controlled vibration damping extends service life and reduces audible disturbances.

Advantages

The clamp combines a rigid steel band with a molded rubber damper to deliver vibration isolation without sacrificing secure fixation. Its 125 mm diameter fit ensures consistent contact and even load distribution around round duct profiles. The rubber insert reduces metal-to-metal contact and helps prevent wear, rattling and structure-borne noise transmission. The design supports straightforward installation and durable performance in HVAC and industrial environments.

Suitable for

• Mounting 125 mm round ventilation ducts and exhaust pipes
• HVAC systems requiring vibration isolation
• Industrial piping where reduction of noise and vibration is necessary
• Wall, ceiling or bracket-mounted duct supports

Key specifications

• Designed inner diameter: 125 mm for round ducts and pipes
• Integrated rubber damper for vibration and noise reduction
• Steel clamp body for secure mechanical fixation
• Suitable for horizontal and vertical mounting orientations
• Compact profile to fit standard ductwork spaces

How to use

Place the clamp around the 125 mm duct or pipe so the rubber damper contacts the duct surface evenly. Align the clamp with the chosen mounting point on the wall, ceiling or bracket, then secure the clamp body with appropriate fasteners for the substrate type. Tighten to provide stable support while avoiding excessive compression of the rubber damper, which could reduce isolation effectiveness. Verify alignment and clearances after installation and check fastener torque to maintain long-term stability.

Usage recommendations

Use corrosion-resistant fasteners appropriate for the installation environment and verify that the rubber damper remains intact during regular maintenance checks. Avoid over-tightening and ensure the supported pipe can expand or contract as required by temperature changes. For noisy or high-vibration applications, combine multiple clamps at recommended spacing to improve overall system damping.
