WELD PIN PROTECTION CAPS
Paragraph 5.6.2 of EN 14125:2004 requires that the terminal pins of electrofusion couplers which are not buried in the ground
shall be closed with plastic caps. The purpose is to prevent any perceived risk of ignition hazard resulting from a static electricity discharge in accordance with EN 14125:2004.
Franklin Fueling Systems Ltd has designed a multi-purpose cap to suit all electrofusion fittings in the UPP® System range. The
design and materials have been third-party tested and certified as fit-for-purpose.
The caps are only required to be fitted when the coupler is in air (not buried) and when an explosive atmosphere is or may be
present, i.e. inside chambers & sumps which are classified as Zone 0, 1 or 2.

Refer to IP 15–IP Model Code of Safe Practice Part 15 Area classification code for installations handling flammable fluids,
2nd edition - for a definition of these hazardous areas.
PIPING &
CONTAINMENT
Weld Pin Protection Caps are compatible with all UPP® fusion elements such as those for primary and secondary pipework and
electro-fusion entry seals. The UPP® System weld pin protection caps have the same fuel resistance as UPP® containment products in which they are deigned to be used.
1. Caps should be fitted AFTER tightness testing is completed.
2. Press one cap firmly over each shroud surrounding the pin.
3. Tap cap with light hammer to ensure it is fully seated.
4. Inspect all of the chamber / sump area to ensure
that all unburied electro-fusion fittings have been
securely fitted with weld pin protection caps.
