Product Information

Self-Grip Door Seal – 25.1mm x 15.5mm

This self-grip door seal is the ideal replacement for MG / Austin-Healey OEM part number KGA817.

This seal is suitable for the following car models:

Austin-Healey Sprite Mk3 (1964-1966)
Austin-Healey Sprite Mk4 (1966-1971)
MG Midget Mk2 (1964-1967)
MG Midget Mk3 (1967-1974)
MG Midget 1500 (1974-1979)
MG MGB Roadster (1962-1980)
MG MGC Roadster (1962-1980)

The U clip can be easily pressed over the edge of the door and is held in place without adhesive due to the natural gripping force of the product. The steel core ensures that the seal holds its shape while offering added protection.

This seal can be cut-to-size with sharp scissors, and offers great flexibility meaning it can easily bend around tight corners or complex angles for sealing or blocking out elements in tight spaces.

Compression Values

After installing this seal, it is important to ensure that the compression of the sponge part does not exceed a maximum of 50%. Exceeding this can greatly affect the overall compression and recovery of the product. An ideal compression rate should be between 30-40%, as this allows the product to return to its original state. If the sponge part of the profile has two sections, this value should apply to each section.

The crucial quality for sealing products is their enduring deformation. This essentially refers to how well the product recovers after you compress it at a specific temperature for a length of time. The most common characteristic is the compression set. In order to determine this value, the sponge part of the product is compressed by 25% and then stored at a set temperature for a predetermined period of time. After the product has been released and left at room temperature for 30 minutes, the height or width (depending on position) is measured and the enduring deformation can be identified. A DVR of 0 would indicate that the test body has reached its original height (unlikely in reality), a DVR of 100% shows that the test body has no recovery and would remain completely deformed.

This is important to note because as the sponge compresses it puts pressure on the seal. After an extended period of time the rubber can deform. If the DVR is too high the elasticity performance and sealing will decrease affecting the performance of the product.
