Thread locking is only one part of a threaded joint. Where the joint must also prevent leakage, a pre-applied sealant forms the sealing interface directly on the thread — an elastic, form-fitting gasket that resists fluids, chemicals and vibration.
Pre-applied sealants work on straight and tapered threads, forming a repeatable sealing interface the moment the joint is assembled — no tape, no paste, no dispensing at the line.
Some applications must seal underneath the fastener head rather than on the thread. The treatment is applied in a controlled pattern under the head, creating a repeatable sealing interface at every assembly.
The sealant conforms to the mating surfaces and stays elastic — resisting fluids, chemicals and vibration.
Suited to both parallel and tapered thread forms, from pipe plugs to sensor bodies.
No PTFE tape, no paste, no dispensing. The component arrives sealing-ready and assembly is one operation.
