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

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.

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.

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™.

Smalley offers thousands of standard

configurations, does not charge for

tooling of non-standard sizes, and in

most cases can provide special orders

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.
