Oetiker 15500033-100 1-ear Clamp 2 Inches

Product Description

The OETIKER 15500033-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from stainless steel, it features a 7 mm band width and 0.60 mm band thickness, delivering consistent clamping force across the full circumference of the connection. The ear closure method creates a vibration-resistant, leak-free seal without requiring worm gear hardware. This clamp is installed by licensed plumbers, HVAC technicians, and refrigeration mechanics using a dedicated ear clamp pincer tool.

The 15500033-100 is suited for residential and light commercial installations where a 2-inch nominal hose or tubing connection requires a low-profile, tamper-resistant clamp. Typical applications include PEX tubing, flexible drain lines, HVAC condensate lines, coolant hoses, and similar soft-tubing assemblies. The clamping range of 48.40 mm to 51.50 mm allows fitment across standard 2-inch nominal OD tubing and hose barb fittings within that dimensional range.

Key Features

• Stainless steel construction resists corrosion in wet and humid environments
• 7 mm band width distributes clamping load evenly to prevent hose deformation
• 0.60 mm band thickness provides consistent elastic spring-back and sealing force
• Clamping range of 48.40 mm to 51.50 mm covers standard 2-inch nominal hose OD
• Single-ear stepless design creates a permanent, vibration-resistant closure
• Ear inner width of 10.00 mm (0.394 inches) compatible with standard pincer tooling

Compatibility

Designed for use on flexible hoses and tubing with an outside diameter falling within 48.40 mm to 51.50 mm, corresponding to standard 2-inch nominal connections. Confirm actual hose OD before installation.

Installation Notes

Installation requires a dedicated Oetiker-style ear clamp pincer or equivalent crimping tool rated for single-ear stepless clamps. Shut off fluid supply and depressurize or drain the line before fitting the clamp. Seat the clamp squarely over the hose barb before crimping to ensure uniform compression. Once the ear is crimped, the clamp is permanent and must be cut off for removal.
