Metpure 3/4″ NOM Rubber Cushion Strut Clamp
These clamps feature zinc-plated steel brackets with an attached bolt and nut that secure a pipe inside a protective rubber cushion. The cushion absorbs vibration and temperature-related movement, helping to reduce noise and prevent galvanic corrosion when mounting copper piping to 3/4″ NOM strut channels. The design allows quick installation by inserting the pipe into the cushion, positioning the brackets on the channel, and tightening the nut onto the bolt.
Metpure 1/2″ NOM Rubber Cushion Strut Clamp
Designed to mount 1/2″ NOM (5/8″ OD) copper piping, this clamp uses zinc-plated steel with a robust rubber cushion to encase the pipe sides. The protective cushion helps dampen vibrations, lowering noise in HVAC runs and protecting against thermal expansion. Mounting is straightforward: insert the pipe into the cushion, align with a 1/2″ NOM strut channel, and secure with the attached nut and bolt.
Metpure 1″ NOM Rubber Cushion Strut Clamp
For larger copper or CVPC piping, this 1″ NOM clamp securely surrounds the pipe using a hard rubber cushion inside steel strut brackets. The zinc-plated hardware resists rust, while the cushion minimizes vibration and incidental noise caused by temperature shifts and flow dynamics. Install by placing the pipe in the cushion, attaching the brackets to 1″ NOM channels, and tightening the bolt and nut.
Forestchill 1/2″ CTS Rubber Cushion Strut Clamp
Forestchill’s 1/2″ CTS clamp emphasizes high-temperature rubber cushioning to absorb shock and reduce noise while insulating pipes from metal surfaces. The zinc-plated steel provides reliable corrosion resistance, and the clamps can be oriented vertically or horizontally for flexible mounting on walls or ceilings, maintaining secure support for copper piping and related tubing.
Forestchill 1″ CTS Rubber Cushion Strut Clamp
This 1-inch clamp extends the same protective and mounting benefits to larger copper pipes. With high-temperature resistant cushioning, it dampens vibrations and minimizes metal-to-metal contact noise. Zinc plating helps resist corrosion, and the clamp supports flexible installation on walls or ceilings for secure, long-term pipe routing in HVAC and plumbing applications.
Linhdor Yellow Zinc 1/2″ CTS Strut Clamp
These Linhdor clamps feature yellow zinc plating and a foam-like cushioning layer that reduces pipe noise and vibration. They’re designed for universal compatibility with multiple pipe types, including galvanized, copper, and gas pipes, with corresponding outside diameters. The yellow zinc finish provides corrosion resistance, while the cushion aids in quiet, stable installations on strut channels.
Linhdor Yellow Zinc 3/4″ CTS Strut Clamp
This 3/4″ CTS Linhdor clamp offers durable yellow zinc plating and a cushioned interior to reduce acoustic and vibrational transfer from pipes to surrounding structures. Its universal fit supports various pipe types, making it a versatile choice for copper piping running through strut channels in tight spaces or mechanical rooms.
LBG Products 6 Pack Rubber Cushion Strut Clamp
These clamps are built for easy installation on copper piping, PEX, and CVPC tubing. The color zinc plating offers corrosion resistance, while the hard rubber cushion reduces noise and vibration. The design supports simple installation with bolts and nuts and is suitable for securing to various strut channels for stable pipe routing in HVAC systems.
Buying Guide: Key Considerations And Comparisons
When selecting strut clamps for copper pipe, consider material durability, vibration dampening, and mounting versatility. Zinc-plated steel provides corrosion resistance in humid environments, while rubber cushions guard against noise and thermal movement. Confirm the clamp’s nominal size (NOM or CTS) matches your pipe diameter, and ensure the clamp is compatible with your strut channel type and pitch. For high-temperature applications, prioritize clamps with high-temperature cushions to maintain performance over time.
Durability vs. ease of installation: Heavier, pre-assembled clamps with attached bolts simplify installation in tight spaces but may require more space for routing. Lighter options with separate bolts can reduce weight but may demand additional hardware.
Noise reduction and vibration control: Cushions are essential for quiet operation in residential settings and commercial mechanical rooms. Rubber cushions with good rebound characteristics and thixotropic properties offer better long-term damping.
Universal compatibility: If your project uses multiple pipe types (copper, galvanized, PVC, PEX), clamps labeled as universal or CTS/NOM-compatible help streamline procurement and installation.
Cost vs. value: While premium clamps with reinforced cushions and zinc coatings cost more upfront, they can lower maintenance and noise-related complaints over time, especially in occupied spaces. Balance budget with durability and installation ease for the best long-term outcome.
