## Long description

The Walraven BIS 2S metal-rubber pipe clamp is a professional-grade solution engineered for the secure mounting of pipes in plumbing and HVAC installations. Designed to accommodate 4-inch pipes with an outer diameter ranging from 113 to 118 mm, this clamp ensures a precise and stable fit.

With its robust metal construction and versatile dual-threaded connection, it provides a reliable foundation for demanding industrial and residential applications.
Advantages
The primary benefit of the Walraven BIS 2S clamp is its superior vibration-damping capability, which is achieved through the integrated EPDM rubber lining. This feature significantly minimizes noise levels within pipe networks, making it an ideal choice for residential buildings where acoustic comfort is a priority. The dual M8/M10 connection thread offers exceptional installation flexibility, allowing for compatibility with various mounting hardware. Furthermore, the durable metal design ensures long-term structural integrity and resistance to mechanical stress, providing peace of mind for professional installers and end-users alike.
Suitable for
Plumbing systems in residential and commercial buildings
HVAC piping installations requiring vibration control

Professional piping projects demanding high stability and acoustic insulation
When it may not be suitable
This pipe clamp is not intended for use with pipes that fall outside the specified outer diameter range of 113-118 mm, as an improper fit may compromise the security of the installation. It is also not suitable for applications involving extreme chemical exposure or temperatures that exceed the thermal resistance limits of the EPDM rubber lining.
Key specifications

How to use
To install the Walraven BIS 2S clamp, first ensure the pipe surface is clean and free of debris. Position the two halves of the clamp around the pipe at the desired mounting location. Align the connection thread with your chosen M8 or M10 mounting rod or bracket. Tighten the side screws evenly to ensure the EPDM lining is compressed correctly against the pipe surface, providing a secure grip without damaging the pipe material. Verify that the clamp is firmly attached and that the pipe is properly supported according to your system design requirements.
What to consider before purchase
Verify the exact outer diameter of your pipe to ensure it falls within the 113-118 mm range.
Check the compatibility of your existing mounting hardware with the M8/M10 connection thread.
Assess the environmental conditions of the installation site to ensure the EPDM material is appropriate.
Usage recommendations
For optimal performance and longevity, ensure that the clamp is tightened to the manufacturer's recommended torque settings and that the pipe is adequately supported by additional brackets if the span between supports is significant.
