4th Generation MAXIMUM Flow
Self Venting Gas Injectors
Ideal for Gas Injection Into
Radiused Surfaces
AEGIS' AG4 Series Gas Injector is designed for the maximum possible N2 gas flow, while providing complete venting capability for maximum pressure profiling ability. The AG4 has no "shoulder" or hex at the base, which provides a clean 1/4" hole at the gas injection point into the molding. Ideal for recreational products, furniture or anywhere that a clean gas injection point is desired.

A3SC Series End Discharge Gas Assist Injectors
O1 Tool Steel Construction; 316 Stainless Steel Available
Enhanced durability and enhanced flow self cleaning gas injector. Assembles into tool without removal from the molding machine, with ¼-20 threads. Improved flow-center element provides increased gas flow over any previously available gas injector, plus self-cleaning capability. Stainless steel construction is normally only recommended when molding corrosive resins such as PVC or other flame retardant resins. This new product is a direct remove and replace for older gas injectors with a 3/8" diameter "shoulder" and 1/4-20 threads. Furnished with (5) spare O-rings.

A6SC Series Durajector™ - The most durable, high flow, self cleaning gas assist injector...ever.
O1 Tool Steel with specialty titanium nitride coating
Undisputedly the most durable gas assist injector in the industry, with enhanced flow and excellent self cleaning capabilities.
Engineered for use with reinforced resins where fiberglass, calcium carbonate, talc etc. cause wear in many gas assist applications. Assembles into tool without removal from the molding machine, with ¼-28 threads. Improved flow-center element provides increased gas flow over any previously available gas injector, plus self-cleaning capability. The A6SC Series Durajector is designed to provide a smaller overall body diameter for any application, and requires no O-ring. Especially suited for tool applications where a smaller diameter is needed. AEGIS recommends the A4SC or A6SC Series for all new tool builds. Custom dimensions available. Durajectors™ are available only from AEGIS.

Aftermarket Replacement Gas Injectors |
DET-0001ACE End Discharge Replacement Gas Assist Injectors
Alloy Steel Construction; Stainless Steel Special Build
The DET-0001ACE is a direct replacement for gas injectors in some existing molds. Low cost, durable, but not recommended for new applications. 8-32 threads. We recommend replacement of this style injector with AEGIS' A3SC or A4SC Series or NitroJection's DET21 Series gas injectors for improved gas flow and AEGIS' exclusive self cleaning function.

DET-0016ACE End Discharge Replacement Gas Assist Injectors
Alloy Steel Construction; Stainless Steel Special Build
The DET-0016ACE is a direct replacement for gas injectors in some existing molds. Low cost and durable, but not recommended for new applications. 1/4-28 threads. We recommend replacement of this style injector with AEGIS' A3SC or A4SC Series or NitroJection's DET21 Series gas injectors for improved gas flow and AEGIS' exclusive self cleaning function.

DET-AGA1 End Discharge Replacement Gas Assist Injectors
Alloy Steel Construction; Stainless Steel Special Build
The DET-AGA1 is designed to replace gas pins that were used long before current designs with self cleaning features and high flow capability were developed. We do not recommend these for new applications, but they are the best units available in the industry for direct replacement in older applications. We can also assist you in converting to later design injectors, which will eliminate having to remove the mold from the molding machine for cleaning or replacement, as this design requires.
