Oetiker 15500015-100 1-ear Clamp 1 Inch Stainless Steel

Product Description

The OETIKER 15500015-100 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 7 mm band width and 0.6 mm wall thickness, this clamp delivers consistent radial clamping force when crimped with the appropriate ear-closing tool. The 1-ear design collapses uniformly during installation, creating a leak-resistant seal without over-stressing the hose or fitting. It is sized for a nominal 1-inch connection with a clamping range of 22.8 mm to 25.6 mm, making it suitable for snug fitment on standard PEX, rubber, or corrugated tubing in that diameter range. Licensed plumbers and HVAC technicians are the primary installers of this clamp style.

This clamp sees common use in residential and light commercial plumbing systems, radiant heat installations, PEX water supply lines, and HVAC condensate and refrigerant-line connections. The 1-ear single-use design is widely used where a permanent, tamper-evident connection is required and where re-usability is not a factor. The stainless steel construction makes it appropriate for both wet and corrosive environments, including potable water systems where material compatibility is critical. Always verify that hose or tubing outer diameter falls within the 22.8 mm to 25.6 mm clamping range before installation.

Key Features

• 1-ear stepless design provides uniform radial clamping force when crimped
• Stainless steel construction resists corrosion in wet and chemical environments
• 7 mm band width distributes load evenly across the hose surface
• 0.6 mm wall thickness maintains consistent ear geometry during crimping
• Clamping range of 22.8 mm to 25.6 mm suits standard 1-inch nominal tubing
• Ear inner width of 9 mm accommodates standard pincer-style ear-closing tools

Compatibility

Designed as an OEM-style stepless ear clamp for 1-inch nominal hose and tubing connections where the outside diameter falls between 22.8 mm and 25.6 mm, typical in PEX plumbing, HVAC, and fluid-handling assemblies.

Installation Notes

Installation requires a dedicated ear-closing or pincer tool rated for 1-ear stepless clamps — pliers or substitute tools will not produce a reliable crimp. Shut off water supply or system pressure and depressurize the line before installing or inspecting clamp connections. This is a permanent, single-use clamp and cannot be reopened or reused once crimped. Follow applicable IPC and local plumbing code requirements for connection type and material approval in potable water applications.
