Slip rings are small but mighty devices that serve multiple purposes and can be used in various industries. They come in different types, shapes, and sizes and are installed where the stationary part of a machine meets a rotational part. Basic designs include rings that rotate with the rotating part of the machine and static […]
Fittings / Couplings
Flange coupling offers higher torques for mobile machinery in same size
For hydrostatic drives in construction and agricultural machines, I. C.-engines and hydraulic pumps are directly coupled. Both units are connected by a flange coupling. This connection must meet a number of requirements — although primarily it must transmit the power reliably, enabling the machine to perform the pending operations as requested. This is done via […]
Holmbury couplers make simultaneous hydraulic connections
The MP series of multiplate couplers from Holmbury, Eastlake, Ohio, lets users simultaneously connect multiple hydraulic lines. The MP Series inherits the benefits of Holmbury’s flat-face coupler design. The product is currently available with a 4- or 6-port design. The devices feature connect-under-pressure male couplers that permit bidirectional flow. The couplers are circlip mounted and […]
Block coupler makes quick work of attachment change-out
Operator safety and failing hydraulic systems have led to a new decompression block coupler from Holmbury. The HDB is designed for the quick change of hydraulic attachments for skid steer, compact and backhoe loaders—as well as compact utility vehicles. The decompression feature allows the operator to alleviate trapped pressure allowing for quick and easy connection […]
Kurt 6W Couplings for rugged high-pressure applications
Kurt Hydraulics line of 6W couplings combined with high pressure braided hose are ideally suited for applications that require high pressure capabilities and temperature ranges from -40° to 250° F for the Oil, Mining, and Heavy Off-Road Equipment Industry. The Kurt 6W couplings are a one-piece, bite the wire crimp coupling with non-skive design to […]
Hydraulic fittings and flanges in mobile equipment
By Josh Cosford Few, if any, fluid power applications would exist without a method to join the “non-standardized standards” of the plumbing requirements of the components in a system. Like an evolved species of the same genus, separated through generations and geography, the long-lost cousins constituting the fittings family tree are as varied as any […]
New hydraulic adapters, fittings and mobile app from Brennan Industries
Brennan Industries Inc., Solon, Ohio, is expanding its product line just in time for IFPE, with new stainless-steel O-ring face seal and flange adapters, custom-made fittings, and even an expanded mobile app for product selection. Because they offer high corrosion resistance and sealing for critical, harsh-duty applications, the new adapters “are ideal in facilities alongside […]
Tompkins’ Metric Compression Hydraulic Adapters
Tompkins metric compression adapters ensure strong, reliable, and leak-free connections. With a cutting ring design highly resistant to vibrations, they are perfect for pressue applications and temperatures ranging -40° F to 392° F. These compression fittings are available with a wide selection of shapes, sizes and port threads to meet your application needs. They are […]
Parker Releases Multi-Platform App to Simplify Identification of Part Numbers
Parker Hannifin Corporation’s Tube Fitting Division recently launched Parker FittingFinder, an innovative mobile, tablet and Web-based App that brings the hydraulic tube fitting and adapter identification process to users’ fingertips. The App allows customers to quickly and easily identify and locate fittings by selecting the fitting’s shape, end type, size and material. Using that information, […]
Technical Standards Now Available From NFPA
Three technical documents have recently been published and are now available from the National Fluid Power Association (NFPA). ISO 6162-1:2012 (supersedes ISO 6162-1:2002) Hydraulic fluid power – Flange connections with split or one-piece flange clamps and metric or inch screws – Part 1: Flange connectors, ports and mounting surfaces for use at pressures of 3,5 […]
