pipe thread sealants

Hernon's line of Dripstop(TM) 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(TM) 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.

Grade numbers 920, 940, and 427 (see Thread Locking Section, Page 12), have been tested and classified by the Underwriters Laboratory's (UL) File Number MH14222.

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.

Because the sealant path is formed when parts are made-up, that is, threaded together, the plastic shim formed during cure is truly a "custom" seal. Sealant not forced out cures to a helical path in the thread roots to form an exacting match of the surface irregularities. The shim mirrors and fills all the voids, scratches, and thread nicks present in even the best machined straight or pipe threads. Unlike Teflon(R)+ tape, any non-confined or excess sealant material does not cure and pose the threat presented by shredded tape fouling valves or circuit elements.
