Technician a says that a seal can be pried out of a bore using a sharp chisel. technician b says that smaller metal-backed seals can often be driven into place using a standard socket. who is correct? group of answer choicesa. a onlyb. b onlyc. bothd. neither

The correct answer is letter "C": Both.

Explanation:

Industrial seals are used at interfaces between components to prevent leakage, to maintain heat, and to avoid contamination. The design, construction, and materials they use vary depending on industrial use but the most common are Polytetrafluoroethylene (PTFE), Nitrile Buna Rubber (NBR), and fluorocarbon.

Thus, using a sharp chisel could pry a seal out of a hole and a regular socket can often be used to force smaller metal-backed seals into place. Thus, technicians "A" and "B" are correct.
