Clamp Body Materials
Clamp bodies are typically made from thermoplastics or aluminum, each designed to handle specific temperature and environmental conditions.
Polypropylene Clamp Bodies
Rated for continuous use up to 194°F (90°C), polypropylene is ideal for standard applications where temperature and stress levels are moderate. It’s resistant to many chemicals and works well for hydraulic and pneumatic systems, especially indoors or in controlled environments.
Available in Light Series Green, Light Series Blue, Heavy Series, & Twin Series configurations.
Polyamide (Nylon) Clamp Bodies
Polyamide clamp bodies offer higher thermal and mechanical resistance, with a max operating temperature of 248°F (120°C). If your system runs hotter, or if vibration is a factor, nylon is a solid step up from polypropylene. It’s commonly used in heavy-duty industrial equipment and outdoor installations.
Available in Light Series configurations.
Aluminum Clamp Bodies
Need something tough enough for extreme conditions? Aluminum clamp bodies are built for it. They can handle both hot and cold extremes without degrading — making them ideal for steel mills, outdoor systems, or applications with high mechanical loads and frequent temperature swings.
Available in Light Series and Heavy Series configurations.
The best part? Our clamps are modular.
That means you can mix and match body materials and hardware types to build the perfect configuration for your system. Whether you need a polypropylene clamp with 316 stainless steel bolts, or an aluminum clamp with carbon steel plates — we can make it happen.
Clamp Hardware Materials
The weld plates, cover plates, and bolts are where the real holding power happens. Choosing the right metal ensures your clamps stay secure — especially in challenging environments.
Carbon Steel (Zinc-Plated or Plain)
Carbon steel is the most economical and widely used option. Zinc-plated versions add basic corrosion protection, making them suitable for general indoor use. For outdoor systems or humid environments, you may want to upgrade to stainless.
Available in Light Series, Heavy Series, & Twin Series configurations.
304 Stainless Steel
A go-to for water systems, food and beverage processing, and clean industrial applications. 304 stainless is rust-resistant and easy to clean, but it may show signs of corrosion in salt-heavy or chemical-heavy environments.
Available in Light Series configurations.
316 Stainless Steel
The most corrosion-resistant option we offer. 316 stainless steel holds up in coastal, offshore, or chemical environments where others would fail. It’s ideal for marine-grade systems, chlorinated water lines, and harsh outdoor installations.
Available in Light Series, Heavy Series, & Twin Series Configurations.
