gas pin A3SC Series

A3SC Series End Discharge Gas Assist Injectors


Tool Steel Construction; Stainless Steel Special Build


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.


A5 Durajector Gas Pin

A5SC Series Durajector™ - The most durable, high flow, self cleaning gas assist injector...ever.


O1 Tool Steel with specialty titanium nitrite 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 ¼-20 threads. Improved flow-center element provides increased gas flow over any previously available gas injector, plus self-cleaning capability. 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.  Durajectors™ are available only from AEGIS.


A6 Durajector Gas Pin

A6SC Series Durajector™ - The most durable, high flow, self cleaning gas assist injector...ever.


O1 Tool Steel with specialty titanium nitrite 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, 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.

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.

Past production AEGIS Gas Assist Injectors



APS1 Series End Discharge Gas Assist Injectors


Hardened Steel or Stainless Steel Construction


Assembles into tool without removal from the molding machine, with ¼-20 threads. Indexing-center element allows for increased gas flow and self-cleaning capability. Available in hardened steel or stainless steel. Stainless steel is normally only recommended when molding corrosive resins such as PVC or flame retardant resins. - Limited availability! Replaced by A3SC and A4SC Series - see above



AP1 Series End Discharge Gas Assist Injectors


Hardened Steel or Stainless Steel Construction


Assembles into tool without removal from the molding machine, with ¼-20 threads. Available in hardened steel or stainless steel. Stainless steel is normally only recommended when molding corrosive resins such as PVC or flame retardant resins. - Limited availability! Replaced by A3SC and A4SC Series - see above



AP2 Series Side Discharge Gas Assist Injectors


Hardened Steel or Stainless Steel Construction


Assembles into tool without removal from the molding machine, with ¼-20 threads. Available in hardened steel or stainless steel. Stainless steel is normally only recommended when molding corrosive resins such as PVC or flame retardant resins. Note: Side discharge injectors were designed to eliminate a "blemish" on a Class A surface when an end discharge injector might cause this defect. This is not a common problem.  We recommend end discharge injectors for the vast majority of gas assist applications! - Limited availability! Replaced by A3SC and A4SC Series - see above
