GG20 Inspection and Maintenance Schedule: Daily, 6 to 12 Months, 24 Months

Updated 2026-10-07 · Sourced from ELAFLEX documentation

Short answer: ELAFLEX recommends three levels of care for GG1 and GG20 nozzles: a daily visual check by trained personnel (coupling clean and undamaged, swivel turns, nose piece O-ring intact), a full inspection every 6 to 12 months (seals, connector nut and pawl, swivel grub screw, valve movement, leak test with soapy water on a blanked 1¾" ACME adaptor), and a complete seal kit replacement every 24 months. The GG20 series seal kit is listed as GG3.

Daily, by trained site personnel

Coupling is clean and undamaged: no dents, sharp edges or blocked lever.
Inlet swivel rotates.
White nose piece O-ring is free of dirt and mechanical damage.

Every 6 to 12 months

#	Check
1	Any physical damage to nozzle components
2	Connector nut and nose piece seals for cuts or excessive wear
3	Connector nut turns freely; pawl and spring work
4	Inlet swivel is secured by its grub screw
5	Valve slides freely in the slide sleeve: work the lever several times
6	Valve function on a blanked 1¾" ACME adaptor; check nose seal and U-cup seal with soapy water
7	Soapy water leak check at the inlet swivel, nozzle body and valve assembly

Every 24 months

ELAFLEX PACIFIC recommends fitting a new seal kit throughout the nozzle every 24 months to extend service life and cut downtime. The repair manual lists the GG3 seal kit for the GG20 series. Seal replacement is a bench job; see repair and testing.

Keep a log

A simple record per nozzle (serial number, date, who checked, result) makes the 24-month interval easy to track. Where low-emission rules apply, such as South Coast AQMD Rule 1177, facilities must be able to show that connectors meet the rule and are kept vapor- and liquid-tight.

Warranty

The ELAFLEX PACIFIC manual gives a 12-month warranty from date of supply against defective materials and manufacture. It excludes normal wear and improper use, and approvals and warranty are void if non-original parts are used or the nozzle is modified.
