Metpure Rubber Cushion Strut Clamp, 3/4″ NOM (7/8″ OD), 5 Pack
The Metpure clamp is designed for 3/4″ nominal (7/8″ outside diameter) tubing and comes in a 5-pack. It features zinc-plated steel strut brackets with an attached bolt and nut that secure over a hard rubber cushion. The cushion dampens vibration and reduces noise, while insulating the pipe from metal surfaces. This unit is best for projects requiring a robust, corrosion-resistant clamp with simple, secure mounting.
Best for: Applications with vibration, temperature fluctuations, or noise concerns where a sturdy, corrosion-resistant mount is needed.
Why selected: Combines heavy-duty steel with a protective cushion and corrosion resistance, offering reliable long-term performance in challenging environments.
Caution: Ensure the 3/4″ nominal sizing matches your pipe or tube outer diameter to avoid loose fits.

Buying Guide
Key considerations when selecting 3/4 cushion clamps:
- Material and finish: Stainless steel offers superior corrosion resistance, especially in outdoor or marine settings, while zinc-plated steel provides good protection for indoor use.
- Rubber cushion quality: A dense, heat-resistant cushion helps absorb vibration and prevents damage to pipes or cables over time.
- Sizing accuracy: Confirm 3/4″ nominal (or 7/8″ OD) compatibility with your pipe or tubing for a secure fit.
- Mounting method: Look for clamps with simple bolt-through mounting or integrated brackets that fit your strut channels or surface.
- Number of pieces: Consider whether you need a bulk pack for ongoing projects or a smaller kit for a single job.
- Applications: Marine, automotive, HVAC, and DIY projects each have distinct requirements for insulation, moisture resistance, and UV exposure.
- Installation ease: Some designs include pre-attached nuts and easy one-hand tightening, which can save time on installations.
FAQ
- What is the difference between 3/4″ NOM and 3/4″ OD clamps?
Nominal (NOM) sizes refer to the intended pipe size, while outside diameter (OD) specifies the actual pipe diameter. Ensure your pipe’s OD matches the clamp’s intended range for a proper fit.
- Are rubber cushions essential for noise reduction?
Yes. The rubber cushion helps absorb vibrations and reduce metal-to-metal contact, which lowers noise and protects the pipe or cable.
- Is stainless steel better than zinc-plated steel?
Stainless steel offers superior corrosion resistance in harsh environments, such as saltwater or high humidity. Zinc plating is adequate for indoor use with moderate exposure.
- Can these clamps be used for electrical wiring?
Many clamps are designed for both pipes and wires. Check the product features to confirm compatibility with electrical installations and insulation requirements.
- How many clamps should I buy for a project?
Estimate the total length of runs and the number of supports needed. Bulk packs (like 100 or 20 pieces) reduce the need for frequent reorders in larger projects.
