OILCO Liquid Handling Systems

OILCO Liquid Handling Systems Meet the largest continuous line of swivel joints serving heavy industry. 100% manufactured in the U.S. Trusted globally.

OILCO products bring you reliability at every turn. OILCO Liquid Handling Systems has maintained a position on the forefront of innovation in regard to its product line. Traditionally, the bulk transfer and heavy industry standards have not altered much in relationship to the basic component arrangements and their construction. Improvements to seal composition and technology and carrying capacity

have always been paramount to OILCO development. Because of this, the 90 Series swivel joints have maintained an untouchable record in the industry for performance and reliability. To date, no OILCO v-ring swivel joint has failed due to factory error. And based on continuing EPA and OSHA concerns and bio-originated fuel sources, this characteristic has become pivotal in product selection. Recently, OILCO has dedicated all of its research and development time in innovation rather than improvement. Utilizing a combination of tapered roller bearing and a geometrically aligned ball bearing row, the v-ring technology and unparalleled tolerance design, OILCO succeeds in realizing a lofty goal of swivel joint production.

Our 90 Series remains our best-seller, year after year. Here’s why: Quality materials. Precision tolerances. Deliberate design.

The 90 Series was specifically engineered for heavy duty use in steel mills and municipal infrastructure plants. Today, it’s used across heavy industry. With a flared seal, the 90 Series v-ring creates a tremendous increase in the contact patch sealing area. Applying positive, continual pressure, the 90 Series v-ring forces seal adherence at all times.
