ʻO BB moʻo pneumatic hexagonal milo waho i loko o ka milo i loko e hōʻemi pololei ana i ka hui pū lima keleawe he mea hoʻohana maʻamau. ʻO kāna hiʻohiʻona nui, ʻo ia ka mea i hana ʻia me nā mea keleawe a maikaʻi ke kūpaʻa corrosion a me ka conductivity thermal. Eia kekahi, ʻo ka hui pū kekahi he hoʻolālā hoʻohaʻahaʻa o nā kaula hexagonal waho a me loko, hiki ke hoʻokō i nā pilina ma waena o nā kaula o nā nui like ʻole.
Ma ka hoʻohana ʻana i ka BB series pneumatic hexagonal thread waho i loko o ke kaula e hōʻemi ana i nā pono lima keleawe hui pololei, ʻoi aku ka maʻalahi o ka hoʻopili ʻana i nā paipu a i ʻole nā mea hana like ʻole. Hoʻohana nui ʻia ia i nā ʻoihana ʻoihana, e like me nā compressors air, nā ʻōnaehana hydraulic, nā lako automation, a me nā mea ʻē aʻe.
