Hoopster retaining rings launched

in as little as one to two weeks. The company meets international standards including ISO 9001, ISO/TS16949, AS9100 and ISO 14001.

SMALLEY Steel Ring Company, manufacturer and developer of Spirolox ® retaining rings, snap rings and wave springs, has introduceHoopster retaining rings. Hoopster rings are designed to fit into shallower grooves than regular snap rings or retaining rings. The Hoopster’s low profile, precision circularity and small radial size allow it to be an unobtrusive component in an assembly. Hoopster retaining rings are suitable for light to heavy loads, particularly for thin wall tubes. An additional advantage of the Hoopster is its potential for high thrust capacity. The low radial profile will not twist or deform under load as with conventional retaining rings. Hoopster retaining rings are easily installed without special tools. Standard sizes are stocked from 3 / 8 " to 3" and offered in carbon and 302 stainless

steel. Specials can be made with No-Tooling-Charges™.

Barrier pipe service connection directly from a ductile iron main

Fitting the live ferrule off-take is straightforward, using a normal under- pressure drilling machine. A hole is drilled and tapped to accept the ferrule’s ¾" BSPT gunmetal stem and plug. The drill can then be removed and the off-take banjo fitted, complete with a dedicated Protecta-Line mechanical compression end connector to accept the 25mm Protecta-Line service pipe. With all joints securely made, the plug is rotated to open the flow to the service pipe. This new fitting complements the equivalent self-tapping ferrule off- takes for connection to Protecta-Line mains pipe sizes 63mm to 355mm, which were recently introduced by GPS PE Pipe Systems. Featuring the same banjo component and designed to minimise head-loss, these ferrules include a stainless steel saddle clamp for additional security. Both ferrule types provide protection against the ingress of contaminants. The Protecta-Line barrier pipe system has full BSI Kitemarked status to WIS 4-32-19, a water industry standard for the transport of drinking water through contaminated land.

connections, directly from a ductile iron main, to developments on brownfield land. As the gunmetal ferrule can be installed while the main is at normal working pressure, no disruption to the supply is necessary when adding a connection. Compliant with WIS 4-22- 02, the ferrule provides a solution for connecting a 25mm Protecta-Line service to live ferrous mains pipes.

GPS PE Pipe Systems has added an additional live ferrule off-take to its Protecta-Line ® range of barrier pipe and fittings, allowing branch connections from ferrous water pipes to be made quickly and safely. The WRAS-approved ferrule answers water industry calls for a simple way to provide Protecta-Line service
