ND Crushable Mastic Sealer is an extruded product that is specially formulated for fastening and sealing operations that require holes and gaps to be filled and sealed. An extruded product, Crushable Mastic Sealer can be formed in a variety of shapes, sizes, and dimensions, and can be applied to your parts by ND Industries.
ND Crushable Mastic Sealer is most often used in one of two ways. The most common is that of seal, pre-assembled directly to a fastener. Crushable properties enable it to evenly fill and seal holes, gaps, and other voids in bolts, nuts, stampings, or virtually any other item. Using resources specifically designed for this product, ND Industries is capable of bonding Crushable Mastic Sealer to a variety of substrates. The second most common use is as a loose seal. ND forms the material to specifications and the end user or assembler places the seal on the gap, prior to torquing the fastener into place.
Crushable Mastic Sealer can be extruded in a wide range of diameters, lengths, and durometers.
Unlike many other automotive sealers, Crushable Mastic Sealer can be exposed to temperatures of up to 400° F without losing its sealing qualities.
Unlike plastic, rubber, and other washer materials which often fail to seal completely when torqued into place, Crushable Mastic Sealer is crushable and consistently provides reliable gap filling and sealing.
Crushable Mastic Sealer requires no special tools for application by the end user.
Crushable Mastic Sealer is stable, with a long shelf life.
Crushable Mastic Sealer will not stain metal, fabric, or other surfaces.
