Oetiker 15500009-100 1-ear Clamp 11/16 Inch

Product Description

The OETIKER 15500009-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Constructed from stainless steel with a band width of 7.00 mm and a thickness of 0.60 mm, this clamp delivers a uniform radial clamping force when closed with a pincer tool. The 11/16 inch nominal size accommodates a clamping range of 15.10 mm to 17.00 mm, making it suitable for small-diameter flexible hose connections. Licensed plumbers, HVAC technicians, and fluid-system installers rely on this style of clamp where a tamper-evident, vibration-resistant seal is required.

This clamp is used in residential and light commercial systems where flexible tubing must be secured to barbed fittings. Common applications include PEX supply connections, coolant and condensate lines, pneumatic tubing, and similar low-to-medium pressure hose assemblies. Its compact profile allows installation in tight spaces where worm-gear or screw clamps are impractical. The single-ear design is closed once with an Oetiker pincer or equivalent ear-clamp tool, forming a permanent, non-adjustable connection.

Key Features

• Single-ear stepless design provides consistent, uniform clamping pressure around the hose circumference
• Stainless steel construction resists corrosion in wet, humid, and outdoor environments
• Clamping range of 15.10 mm to 17.00 mm suits 11/16 inch nominal hose and tubing
• Band width of 7.00 mm and thickness of 0.60 mm offer a balance of strength and compact profile
• Permanent closure reduces the risk of loosening due to vibration or thermal cycling
• Compatible with standard Oetiker ear-clamp pincer tools for fast, repeatable installation

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 11/16 inch nominal flexible hose and tubing connections in plumbing, HVAC, and fluid-handling systems.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool or equivalent; do not attempt to close the ear with pliers, as uneven force can crack the ear or fail to seat the clamp correctly. Shut off fluid flow and depressurize the line before removing any existing clamp or fitting. Verify that the tubing is fully seated on the barbed fitting before closing the clamp, as the connection is permanent once the ear is crimped. This work is typically performed by a licensed plumber or HVAC technician in accordance with applicable local plumbing and mechanical codes.
