Metpure 3/4″ Rubber Cushion Strut Clamp
These heavy-duty steel strut clamp brackets come with attached bolts and nuts, securing over a hard rubber cushion that nearly surrounds the pipe or tube. The zinc plating helps prevent corrosion, ideal for copper piping installations where longevity matters. Attach the clamp to 3/4″ NOM (7/8″ OD) strut channels and tighten for a solid mount. The cushion absorbs vibration and temperature changes, reducing noise and insulating the pipe from metal surfaces to prevent galvanic corrosion.
The clamp is designed for quick installation: insert the pipe into the cushion, secure with the bolt and nut, and mount to the channel. This size is a common fit for residential copper mainlines and branch runs. The combination of steel strength and rubber cushioning offers a balanced solution for moderate vibration environments, such as near pumps or water heaters.
Metpure 1/2″ Rubber Cushion Strut Clamp
The 1/2″ NOM clamp uses a similar construction: zinc-plated steel with a protective rubber cushion, designed to grip 1/2″ copper or PEX piping while minimizing noise and heat transfer. The included bolt and nut system allows straightforward tightening and a secure hold on 1/2″ nominal pipes (5/8″ OD). The cushion serves to dampen vibrations from water flow and temperature fluctuations, helping to maintain quiet operation in tight mechanical rooms or utility closets.
Installation steps are consistent with other sizes: slide the pipe into the cushion, align with a 1/2″ NOM channel, and tighten the nut onto the bolt. The clamp’s durable finish makes it suitable for long-term use in dry, damp, or humid environments common in residential basements or garages. This size is a frequent choice for copper distribution lines and small-diameter PEX runs.
Metpure 1″ Rubber Cushion Strut Clamp
The 1″ clamp expands the protective cushion and steel housing to accommodate larger piping, including 1″ NOM (1-1/8″ OD) copper or CVPC tubing. It maintains the same zinc-plated steel construction with a robust rubber cushion for noise reduction and vibration damping. The mounting procedure remains straightforward: insert the pipe into the cushion, secure to the strut channel, and tighten the bolt and nut. This size is commonly used for main feeders and branch lines in residential layouts requiring a stronger support point.
As with smaller sizes, the cushion protects pipes from metal contact and temperature-induced movement, reducing potential wear on fittings and joints. It’s a practical option for general plumbing risers and vertical runs in closets or utility rooms where motion is more likely. The 1″ clamp provides a reliable, durable solution for moderate-load piping applications.
Forestchill 1/2″ Rubber Cushion Strut Clamp
Forestchill offers a zinc-plated steel strut clamp with a high-temperature resistant rubber cushion. This model is designed to withstand tougher environments where heat from nearby appliances or sun exposure could affect performance. The cushion continues to dampen noise and reduce vibration, while the zinc plating minimizes rust and corrosion over time. It supports copper pipes, PEX, CVPC tubing, and gas piping with compatible outside diameters, making it versatile for mixed-material installations.
The clamp provides dependable support, with the ability to hang vertically or horizontally on walls or ceilings. For installations in garages, basements, or outdoor-rated runs where exposure to moisture is a concern, the Forestchill 1/2″ clamp offers a balance of durability and flexibility for copper and related piping systems.
Forestchill 1″ Rubber Cushion Strut Clamp
This 1″ Forestchill clamp shares the same zinc-plated steel body and cushioned interior designed to handle higher pipe sizes. The rubber cushion provides superior vibration dampening and temperature isolation, helping minimize noise in busy mechanical rooms. The clamp’s sturdy construction supports copper pipes, galvanized tubing, PEX, and gas piping, depending on the OD compatibility. Vertical and horizontal mounting options add flexibility for various installation scenarios, including tight spaces behind appliances or along joists.
Like other Forestchill clamps, the 1″ version emphasizes corrosion resistance, enabling long-term use in environments with humidity or exposure to moisture. This makes it a reliable choice for residential and light commercial projects that require a durable, quiet, and easy-to-install strut clamp solution for copper piping and allied tubing.
Buying Guide: Key Considerations For Strut Clamps
- Pipe Size And OD Compatibility: Choose clamps that match your pipe’s nominal size and outside diameter to ensure a snug fit and secure mounting.
- Material And Finish: Zinc-plated steel provides corrosion resistance, which is important in humid basements or outdoor-covered areas. Consider stainless steel for harsher environments.
- Cushioning Material: Hard rubber cushions dampen vibration and reduce noise; some models offer higher temperature resistance for installations near heat sources.
- Mounting Versatility: Look for clamps that support both vertical and horizontal installations and that fit standard strut channels to simplify integration with existing systems.
- Load And Environmental Conditions: For long runs or heavier piping, select clamps with robust hardware and better load-bearing capacity; consider exposure to moisture, solvents, or salt air in coastal regions.
- Installation Ease: Bolts and nuts should be readily tightened with common tools; fewer parts reduce installation time and potential loss of hardware.
- Compatibility Across Materials: If copper, PEX, or CVPC tubing will co-exist, verify universal compatibility claims and ensure OD/CTS alignment.
Overall, rubber cushion strut clamps offer a practical balance of durability, vibration damping, and corrosion protection for copper piping installations. Consider the environment, pipe size, and install location when selecting clamps to ensure a long-lasting, quiet, and compliant plumbing setup.
