Tadpole Seals

We supply a variety of tadpole seal configurations (also known as P seals) suitable for a wide range of dry heat applications. They are typically used in door sealing applications where extreme operating temperatures normally apply. The type of seal required will often depend on several operational factors, notably the operating temperature of the equipment, and the frequency that the door is opened and closed.

Applications

Tadpole seals are primarily used in oven, boiler, kiln and furnace door sealing applications, often as replacements to oem seals. Tadpole seals can be manufactured using a combination of any outer cover and any bulb as per the availability tables below.

Key Features

Excellent insulation properties.
Bulbs of different compressibilities depending on type.
Glass and ceramic have resistances to oils, solvents and chemicals.
Aramid fibre provides excellent cut and abrasion resistance.

Availability

When enquiring, please specify the size of bulb, width of the tail and overall length required. Double bulbed tadpole seals can also be supplied if required.

Tadpole Seals - Outer Cover Options

Material	Temperature (°C)	Key Features
Glass Fibre	Up to +550	Woven glass yarns with exceptional thermal resistance. Good resistance to oils, solvents, thermal shock and chemicals.
Ceramic Fibre	Up to +1260	Woven ceramic yarns with even better thermal resistance. Good resistance to steam, oils, solvents and chemicals.
Aramid Fibre	Up to +350	Excellent abrasion and cut resistance, high tensile strength, and good dimensional stability.
