GG20 Part Numbers Decoded: Nose Pieces, Inlets and Option Codes

Updated 2026-10-07 · Sourced from ELAFLEX documentation

Short answer: A GasGuard 1¾" ACME part number is built from nozzle style (GG1 or GG20), nose piece (E, H or DN), then options: J magnet, S strainer, L hold-open latch, followed by inlet size. In the ELAFLEX catalogue the GG20 types are GG20.2 / GG20.3, GG20H.2 / GG20H.3 and GG20DN.2 / GG20DN.3, where .2 is ½" NPT female and .3 is ¾" NPT female. Extra suffixes add J (magnet), L (latch), G (splashguard) or B (hard-anodized connector with brass ACME insert). Distributors don't all write these codes the same way, so confirm nose piece, latch and inlet in words before ordering.

How ELAFLEX builds the number

ELAFLEX's Information 6.15 lays the code out in six positions:

#	Position	Choices
1	Nozzle style	GG1 (125 mm reach) or GG20 (160 mm reach)
2	Nose piece	E (single, attended, highest flow), H (hybrid, lower lever force), DN (dual, unattended/public)
3	Magnet	J, only if the dispenser uses a reed switch in the nozzle boot
4	Strainer	S, standard since July 2014
5	Latch	L, optional hold-open latch
6	Inlet size	½" (15 mm) or ¾" (20 mm) NPT female

Catalogue part numbers

Part number	Nose piece	Inlet
GG20.2	Single	½" NPT female
GG20.3	Single	¾" NPT female
GG20H.2	Hybrid	½" NPT female
GG20H.3	Hybrid	¾" NPT female
GG20DN.2	Dual	½" NPT female
GG20DN.3	Dual	¾" NPT female

The GG20 has no "E" in its catalogue code even though it uses the E nose piece. Its shorter sibling is written GG1E.

Option suffixes

Code	Option	Notes
J	Magnet in the front guard	For contactless pump activation where the boot has a reed switch. Not needed otherwise.
L	Hold-open latch (aluminum)	Not covered by the UL listing, and ELAFLEX notes not every country or LPG authority allows a latch. Check with your authority having jurisdiction.
G	Splashguard, soft orange PVC	Shields the hand from gas released after the valve shuts.
B	Special connector	Hard-anodized alloy connector with brass (non-guided) ACME insert, instead of the standard guided stainless insert.
S	Strainer	300 µm / 50 mesh. Fitted as standard on current production.

How US distributors write it

Codes drift between catalogues. Examples seen in US distributor listings: "GG20S" (with strainer), "GG20SL" (strainer and latch), "GG20DNS", and a listing titled simply "GG20" that is described as having a locking latch. Because the latch changes the UL status and the nose piece changes who may safely use it, confirm three things in plain words on every quote: nose piece (single, hybrid or dual), latch (yes or no), inlet (½" or ¾").

Spare assemblies named in the repair manual

Assembly	Part number
Connector assembly	GG27
Lever assembly (with latch)	GG5 (GG5L)
Valve assembly	LG24
Inlet swivel assembly	LG2, 15 mm or 20 mm
Nozzle body assembly	10-1307-715
Strainer	EK172.1
Magnet assembly	GGJ
Seal kit for GG20 series	GG3

These numbers come from the GG20 repair and maintenance manual. Availability of individual spares in the US varies; ask before you plan a repair around one.

Quick answers

What does .3 mean in GG20.3?
