    Description

    By using high strength stainless steel alloys, the weight of a lubricator section is reduced by up to 70% with respect to conventional integral lubricators.

    The NOV Elmar “Lite” lubricator consists of four basic parts: a quick union collar, a male quick union, a lubricator tube, and a female quick union. The quick unions are manufactured in H2S resistant alloy steel to prevent galling.

    NOV Elmar “Lite” lubricators are rated 10,000 psi H2S service. The NOV Elmar lightweight quick unions have been selected for optimum weight reduction and to prevent unsafe cross-string assembly. Upper and lower adapters are available to connect existing equipment. These are rated 5,000 psi or 10,000 psi depending on the type of connection.
