Oetiker 15500018-100 1-ear Clamp 1-3/16 in Stainless

Product Description

The OETIKER 15500018-100 is a single-ear stepless clamp used to create a permanent, vibration-resistant seal on hose and tubing connections. The ear is deformed with a pincer tool to compress the clamp evenly around the hose, producing consistent clamping force without the over-tightening risk associated with screw-style clamps. Constructed from stainless steel with a 7 mm band width and 0.6 mm wall thickness, this clamp is well-suited for fluid, fuel, and pneumatic lines in tight spaces where a low-profile connection is required. HVAC technicians, plumbers, and automotive service professionals all use 1-ear clamps in production and service applications.

This clamp fits nominal 1-3/16 inch hose and tubing with a clamping range of 27.00 mm to 30.10 mm. It is commonly installed on coolant hoses, condensate drain lines, fuel vapor lines, and similar flexible tubing connections in both residential and light commercial systems. The stepless design delivers a uniform 360-degree seal, making it a preferred choice where leak-free performance is critical and a tamper-evident permanent connection is acceptable.

Key Features

• Single-ear stepless design provides uniform radial clamping force around the full hose circumference
• Stainless steel construction resists corrosion in wet and chemically active environments
• 7 mm band width distributes clamping load evenly, reducing hose deformation
• 0.6 mm wall thickness keeps the clamp profile low for confined installation spaces
• Clamping range of 27.00 mm to 30.10 mm suits nominal 1-3/16 inch hose
• Ear inner width of 10.00 mm (0.394 inches) is compatible with standard OETIKER pincer tooling

Compatibility

Designed as an OEM-style replacement or production-use 1-ear stepless clamp for nominal 1-3/16 inch flexible hose and tubing assemblies requiring a permanent, tamper-evident seal.

Installation Notes

Installation requires a dedicated ear-clamp pincer or pincers designed for stepless clamps — do not attempt to close the ear with pliers, as uneven force will compromise the seal. Position the clamp over the hose before seating the hose onto the fitting, then slide the clamp to the correct location before closing. Once the ear is closed, the clamp cannot be reopened and reused; cut and replace if service access is needed. Follow applicable plumbing or mechanical codes for the system being serviced.
