1. Clean the surface Remove any old sealing compound which may be present on the bath close to the tap fixing.

2. The testing result shows that sealing compound performance is good, costs are low, and is suitable for static seal of pipe line and valve under different temperature conditions.

3. Reciprocating sealing compound's friction coefficience is changed by sealing compound construction and pressure.

4. When the application is more critical, and the sealing compound may fail due to high heat or pressure, NPTF Dryseal threads are used.

5. The construction of polysulphur sealing compound became the key procedure for a sewerage treatment plant project due to special function requirements.

6. With NPT threads, after a wrench is applied, slight spaces at the major and minor diameters may exist that would allow the assembly to leak and therefore a sealing compound is used to fill any gaps.

7. Utilities required are only those necessary to heat the sealing compound and any power that might be required to drive the small motor of the acid filling machine.

8. Gaskets shall be mounted free of any kind of sealing compound.

9. As special function is required, the construction of polysulfide sealing compound turns into a key procedure in project of a sewage treatment plant.
