Aptus seals are extruded TPEs. This material combines the flexibility of a thermoplastic with the functional performance and properties of a conventional thermoset rubber. Dual durometer kerf barb allows for easy insertion. Slip coat on the top of the bulb decreases operating force in sliding and sweeping applications. Compression seal for a mounting distance between .138" & .250" with a bulb diameter of .275".
Flexible bulb acts as a mechanical seal with little resistance. Conforms to the shape of the sealing surface better than a rigid part.
