ʻO ka hui ʻana i kahi hōʻike hōʻike, i hana ʻia me nā mea kila kuhili ʻole me nā pilina leak-leak a hiki i 400 bar pressure, he ala maikaʻi loa ia e nānā ai i ke kaomi, kahe koko, a i ʻole ka lawe ʻana i nā laʻana.
Hoʻopaʻa ʻia nā mea hoʻopili paipa British Parallel i nā pilina hydraulic hilinaʻi me ka hoʻohana ʻana i nā pae ISO 228-1 a me nā awa ISO 1179.
Hoʻopili kēia metric pololei i ka ISO 261 a loaʻa iā ia kahi kihi 60deg me nā awa e like me ISO 6149 a me SAE J2244.
Hōʻike ka EMA Gauge Adapter i kahi male JIC a i ʻole SAE threaded end, e hiki ai ke hoʻokomo maʻalahi i ka ʻōnaehana hydraulic, a me kahi kaula wahine a i ʻole ka wehe koke ʻana i ke awa, kahi e hoʻokomo ai i ka mīkini kaomi a i ʻole nā mea hana diagnostic ʻē aʻe.
ʻO ka SAE Straight Thread Test Port Coupling e hōʻoiaʻiʻo i kahi pilina paʻa a me ka leak-proof, aʻo ka hoʻohui ʻana i ka awa hoʻāʻo e hiki ai i ka hoʻokomo maʻalahi a me ka wehe ʻana i nā mea diagnostic.
Hoʻolālā ʻia ʻo Male Pipe Thread Test Port Coupling e hoʻopili i nā ana kaomi a i ʻole nā mea hana diagnostic ʻē aʻe i ke awa hoʻāʻo o kahi ʻōnaehana hydraulic, hiki iā ʻoe ke ana i ke kaomi, kahe, a me ka mahana.
