Quick answer
The E19-34 single hose clamp fits hoses from 25mm to 38mm (about 1-1/2"), a common size for pump suction and discharge, drain and irrigation hoses.
Mid-size hoses on pumps, drains and irrigation systems need a clamp that holds firm under pressure and vibration. The 1-1/2" single hose clamp (E19-34) fits hoses in the 25mm-38mm range.

Typical applications
- Water pump suction and discharge hoses
- Sump and drain hoses
- Irrigation and farm water lines
- Pool and pond equipment
Choosing the right clamp
- Fit the hose onto its barb or pipe.
- Measure the hose's outside diameter at the clamp position.
- Pick a clamp with that size within its range, ideally mid-range.
If your measurement is near the top or bottom of the range, consider the next size up or down.
Installation tips
- Place the clamp over the barb, not past it.
- Tighten evenly until the hose is firmly gripped.
- On suction lines, a leak lets in air and the pump loses prime, so make sure clamps are tight.
Maintenance
Check clamps on pumps every few months. Vibration can loosen them over time.
Also available: 1", 2" and 3" single hose clamps at Maintenance Depot.
