Nashua 386 Stretch & Seal Tape, is a self-fusing (an adhesive-free tape that fuses only to itself) silicone rubber tape suitable for dozens of applications where a good water-tight seal is needed. Applications for Nashua Stretch & Seal include: sealing pipes, electrical wiring, wires and hoses; covering sharp edges; protecting against rust and corrosion; wrapping tool handles; marking chain and rope.

Nashua 386 creates an instant, permanent water-tight seal and can withstand temperatures from -60°F to +500°F. Chemical and UV resistant. Can be kept in vehicles for emergency hose repairs. Easy to apply and to remove; no sticky residue left on surfaces. When applying the tape make sure it overlaps itself (since it only adheres to its own backing) and stretch/pull the tape tightly around the object.

NOTE: Nashua has discontinued 386 in clear and only black is currently available for purchase.
