GasGuard Family Compared: GG1, GG20, GG30, GG40 and ZVG 2
Short answer: Pick the nozzle by the fill valve. 1¾" ACME: GG1 (125 mm reach) for normal fill points, GG20 (160 mm) for recessed ones like forklift cylinders and RVs. Bayonet (EN 12806): GG30. K15 / Euro quick connect used on new US vehicles: GG40, or the ZVG 2 EURO UL. The ACME nozzles share nose piece options (single, hybrid, dual) and ratings.
| Model | Fill point | Reach | Flow | Release on closure | Weight |
|---|---|---|---|---|---|
| GG1E / GG1EH / GG1DN | 1¾" ACME | 125 mm | Up to 63 L/min | 1.9 / 1.7 / 1.7 cm³ | ≈1.8 kg |
| GG20 / GG20H / GG20DN | 1¾" ACME, recessed | 160 mm | 63 / 60 / 60 L/min | 1.9 / 1.7 / 1.7 cm³ | ≈2.0 kg |
| GG30 | Bayonet, EN 12806 | 150 mm | 60 L/min | 2.2 cm³ | ≈1.9 kg |
| GG40 | K15 quick connect (US/Canada) | n/a | See ELAFLEX GG40 brochure | ||

GG1 or GG20?
Same function, same nose pieces, same ratings. The GG20 adds 35 mm to the connector nut. If a GG1 bottoms out on a bracket, cradle or body panel before the threads engage, you need the GG20. If it doesn't, the GG1 is lighter and shorter to handle.
Where the others fit
The GG30 serves bayonet fill points and has a 4-slot front and redesigned nose piece; ELAFLEX states it reduces released gas on closure by 23% versus its predecessor. The GG40 was designed for the US and Canadian K15 quick-connect systems and fits the same NB-GG boot. The ZVG 2 EURO UL is ELAFLEX's push-on nozzle; latched versions are covered by UL 125 and UL 567.
