Tight-Seal Vibration-Resistant Pinch Clamps for Firm Hose and Tube
Unlike other pinch clamps, these have a unique tongue-and-groove design that creates a gap-free seal to reduce leaks.
A reinforcing dimple in the ear creates a spring-like action that allows these clamps to withstand vibration and temperature changes without loosening. Also known as ear clamps, they install by crimping the pinch point with pinch-clamp pincers. Clamps are for firm plastic and rubber hose and tube. They are 304 stainless steel for very good corrosion resistance.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.

Vibration-Resistant Chemical Hose with Flanges
- Temperature Range: -65° to 500° F
- Maximum Vacuum: 29" of Hg @ 72° F
- Material: 304 Stainless Steel with PTFE Liner
- Both Fittings Swivel Until Tightened
Transfer harsh chemicals while reducing vibration that could damage pumps or other equipment. This hose is made of corrugated stainless steel and reinforced by a stainless steel braid, so it absorbs vibration instead of passing it on. Also known as a pump connector, it comes in lengths that are commonly attached to pumps. The PTFE liner resists cracking or weakening from some of the most corrosive chemicals, including sulfuric and hydrochloric acid. There’s no need for a gasket because the liner flares out as it passes through the flanges, keeping your line’s contents from touching the fittings. For easy bolt alignment, the flanged ends swivel.
