Oetiker 15500031-100 1-ear Clamp 1-7/8 Inch Stainless Steel

Product Description

The OETIKER 15500031-100 is a single-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. The clamp features a 1-7/8 inch nominal size with a clamping range of 45.40 mm to 48.50 mm, making it well suited for medium-diameter hose work. The band is 7.00 mm wide and 0.60 mm thick, constructed from stainless steel for corrosion resistance in wet and high-humidity environments. Installation requires a standard ear-clamp pincer tool to crimp the ear and create a uniform, leak-free seal. Licensed plumbers, HVAC technicians, and mechanical contractors commonly use this style of clamp on PEX, silicone, and rubber hose assemblies.

This clamp is used in residential and light commercial installations where a tamper-resistant, one-time crimped connection is preferred over reusable worm-gear clamps. Typical applications include PEX tubing connections, coolant hose assemblies, and low-pressure fluid transfer lines. The stainless steel construction makes it appropriate for both indoor and outdoor installations where moisture exposure is a concern. This item is sold individually but carries a minimum order quantity of 10 units.

Key Features

• Single-ear stepless design creates a uniform 360-degree seal when crimped
• Stainless steel construction resists corrosion in wet and high-humidity environments
• 7.00 mm band width provides broad contact area to reduce hose deformation
• 0.60 mm band thickness balances flexibility during installation with holding strength after crimp
• Clamping range of 45.40 mm to 48.50 mm suits standard 1-7/8 inch nominal hose and tubing
• Compatible with standard ear-clamp pincer tools used in plumbing and HVAC service

Compatibility

Designed as an OEM-style replacement or new-installation ear clamp for 1-7/8 inch nominal hose and tubing connections in plumbing, HVAC, and fluid-handling assemblies where a stepless crimped clamp is specified.

Installation Notes

Installation must be performed with a calibrated ear-clamp pincer or crimping tool rated for this clamp style. De-energize or depressurize the associated system before removing any existing clamps or fittings. Once crimped, the ear clamp is a permanent fastener and cannot be reused. Follow applicable plumbing or mechanical codes, including IPC and local amendments, for hose and fitting connection requirements.
