Dripstop®

HERNON®’s line of Dripstop® sealants for plumbing, refrigeration and hydraulics are engineered with many advantages over conventional pipe dopes. These materials harden without shrinkage in the joints creating a tough, insoluble, vibration proof seal that will not leak even if threads are damaged.

Dripstop® sealants are 100% active containing no solvents to evaporate. They do not shred like tape dope and they are not subject to cold flow, pressure and temperature phenomena like non-hardening dopes.

Anaerobic pipe sealants/adhesives are superior to other sealing methods. They contain no solvents and do not shrink, stretch, split, rot, distort, wear-out, or relax and joints never loosen under vibration. Pressure cycling does not weaken or loosen the sealant path.
