Oetiker 10500332-100 1-ear Clamp 1-5/8 in Carbon Steel

Product Description

The OETIKER 10500332-100 is a single-ear stepless clamp designed to create a secure, vibration-resistant connection on hose assemblies, tubing, and flexible conduit. Formed from carbon steel with a zinc-plated head coating, this clamp has a 7 mm band width and 0.75 mm wall thickness. The single-ear design allows the clamp to be crimped with standard ear-clamp pliers, collapsing the ear uniformly to lock the connection without over-stressing the hose wall. This style is widely used in automotive, plumbing, HVAC, and industrial applications where a permanent, low-profile clamp is required.

This clamp suits nominal 1-5/8 inch diameter hose and tubing connections with a clamping range of 37.90 mm to 41.00 mm. It is appropriate for residential and light commercial applications where a one-time, tamper-evident seal is preferred over a reusable worm-gear clamp. Typical install scenarios include coolant lines, heater hose fittings, condensate drain tubing, and barbed fitting assemblies. The minimum order quantity is 10 units.

Key Features

• Single-ear stepless design provides uniform radial clamping force without hose damage
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7 mm band width distributes load evenly across the hose bead
• Clamping range of 37.90 mm to 41.00 mm suits 1-5/8 inch nominal hose diameter
• Low-profile ear sits flush after crimping, reducing snag points in tight installations
• Compatible with standard single-ear clamp crimping pliers or pincer tools

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 1-5/8 inch nominal diameter hose and tubing assemblies across HVAC, plumbing, and light industrial applications.

Installation Notes

Installation requires dedicated ear-clamp crimping pliers or a ratcheting pincer tool rated for the clamp gauge. Before installing, confirm the hose or tubing is fully seated past the barb or fitting bead. Once the ear is crimped, the clamp is permanent and cannot be reopened without cutting. Always de-pressurize and drain the line before servicing any clamp on a fluid-carrying assembly.
