Size 20 SmartSeal Constant Torque Hose Clamp - 1-1/8" - 1-9/16" Hose OD

SmartSeal® provides spring compensation over a full 360° of hose circumference. This is a self-adjusting, all stainless steel clamp that forms a unique 360° seal in response to pressure and temperature changes.
The improved clamp roundness eliminates leak paths, and the exclusive trough-shaped design creates higher pressure loading.

Comprised of two main parts, the clamp assembly and the high quality thin gauge ridged liner, SmartSeal grips by penetrating deeper into the hose wall over a narrower footprint. The result is an optimal heavy-duty constant tension clamp without all the bulk.
The smooth liner is also easy on softer hoses.

Applications include vehicle fluid applications, radiators, turbo-charged engines, solar panels, vehicle HVAC, generators, domestic washing machines and air conditioners, and anywhere else hoses are subject to temperature changes as part of their service application.
