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.
