* A Buna-N (NBR) gasket is used as standard.
*We recommend using couplers and adapters made of the same size and material when connecting fittings. Using couplers and adapters made of different materials may lead to corrosion (electrical corrosion).
*Do not use the dust cap for pressure-resistant applications.
