What do I do when not identifying pressure class before sealing method?

Sealing, Leakage, Mastic & Pressure Testing.1 field-polished — seal/test detail check

Pressure class and seal class decide what needs sealed and how. If you do not know the seal class, ask before choosing a product.

Do not choose a seal method before identifying the system requirement.

Higher pressure or specified systems can require more than a normal surface bead.
