Description
Bop Parts VBR Резиновый Уплотнение Переменный Bore RAM В сборе
CAMTOP Industry Co., Ltd lately for preventing the blowout. The packing element is combined by the main body which is made up of the independent innovation rubber based polymer alloy material and the high strength metal frame, which conforms to the USA 16A, SATM D412, D624, D2240 and D471 standard. It is suitable for the drilling work on the oil field, which shares a high cost performance comparing to the other same type packing elements. And the repair seal kits are equipped.
