Will LOCTITE thread sealant be able to withstand pressure >200 bar?

Yes. LOCTITE thread sealants can take pressures upto 689 bars on a conservative basis and with dimensionally stable threaded assemblies, LOCTITE thread sealants can be used at upto 1000 bar.

Do Loctite products contaminate the fluid media?

LOCTITE products when cured, harden into a thermoset plastic which does not mix with the fluid media that is flowing through the pipe. Hence there is no contamination. If some materials remain cured, they get dissolved in fluid media.

How do I know whether LOCTITE thread sealant is compatible with the fluid or not?

LOCTITE thread sealants are compatible with a wide range of fluid. Please check the Fluid Compatibility Chart for the concerned fluid.

Can I use LOCTITE thread sealant on pipes that carry oxygen or other strong oxidizers?

We do not recommend the use of LOCTITE anaerobic thread sealants for fluid media like oxygen. However, we do have a special variant which is compatible with such media. Please contact us for more details.

Can the curing of LOCTITE thread sealant be expedited?

Yes. In case you need immediate testing, use LOCTITE 55 which once wrapped around the joint, gives instant sealing.

How to disassemble a joint which has been sealed with LOCTITE thread sealant?

It is easy to disassemble joints sealed with LOCTITE thread sealants with standard hand tools. In case that is not sufficient, use localized heat upto 250 degrees celsius, and disassemble while hot.

When is a LOCTITE thread sealant fully cured?

The cure speed of LOCTITE thread sealant depends upon the thread material, thread size and temperature. For fine thread sizes, full cure can be obtained within 24 hours. For faster curing requirement, use of Primers 7649 or 7471 is recommended. Please refer to Technical Data Sheet of the chosen product for further details.

Since the LOCTITE thread sealants are liquid, will they create a mess during operations?

LOCTITE thread sealants are thixotropic in nature and hence will not flow to other areas. Also, LOCTITE thread sealants come with a nozzle for precise application on the joint engagement area. Hence, there is no scope for a mess. In case of any additional amount coming out of the nozzle, you can wipe it off easily because as long as LOCTITE thread sealant is in contact with air, it will remain a liquid and not cure at all.

When should a Primer be used with LOCTITE thread sealants?

It is highly recommended to use Primers 7649 or 7471 with inactive thread surfaces like stainless steel, aluminium, plated surfaces etc., to ensure complete seal. Also, use of Primers is recommended in case you need faster curing.

Which thread sealant is best for plastic joints?

LOCTITE 55 Pipe Cord is the best for sealing plastic joints.

What is the difference between a threadlocker and a thread sealant?

LOCTITE threadlockers and thread sealants have each been developed for specific applications and purposes. Threadlockers lock and seal threaded parts to provide higher locking strength, Whereas, thread sealants seal threaded parts so that they can withstand higher fluid pressures.

Some thread sealants are liquid while others are in thick paste form. Are liquid thread sealants good for sealing?

Yes. Liquid thread sealant is used for hydraulic and pneumatic systems that normally have filters inside. These liquid sealants contain no fillers or particles and therefore there is no need to be concerned about clogging the filtering system or contaminating system fluids with the filler particles. Hydraulic and pneumatic threads are very fine and have a tight fit. Liquid sealants provide an excellent sealing in this case.
