Description

The Mosmatic DYG Swivel 57.351 (90° configuration) is a high-performance brass swivel designed for high-pressure, self-rotating cleaning applications. With a durable nickel-plated finish and corrosion-resistant construction, it is ideal for surface cleaners, parts washers, and tire cleaning systems. This swivel features a precision-engineered triple bearing system—two radial ball bearings and one thrust bearing—ensuring smooth, stable rotation even under continuous high-pressure use. The integrated carbide seal system offers superior leak resistance, while the 90-degree bulkhead design allows for secure and space-saving mounting in tight applications. Built for longevity, this swivel is completely maintenance-free.
