A gas spring seal cap (600A;600B;600C;600D) dimensioned for securement to an associated end member (500;504;506), said gas spring seal cap (600A;600B;600C;600D) comprising: a seal cap body having a longitudinal axis and extending radially outward from along said longitudinal axis, said seal cap body at least partially formed from a substantially nonelectrically conductive material and including: a first end surface portion disposed along a first side of said gas spring seal cap (600A;600B;600C;600D); a second end surface portion disposed along a second side of said gas spring seal cap (600A;600B;600C;600D) that is spaced longitudinally from said first side and facing opposite said first end surface portion; and, an outer peripheral surface portion disposed between said first and second end surface portions (614,612); and, a first electrical conductor and a second electrical conductor extending through said seal cap body, each of said first and second electrical conductors (616,618) formed substantially of electrically conductive material directly embedded within said seal cap body without permitting conductive cross-communication between said first and second electrical conductors (616,618) through said substantially nonelectrically conductive material, each of said first and second electrical conductors (616,618) disposed radially inward from said outer peripheral surface portion and including: a first terminal end (616B,618B) conductively accessible from along said first end surface portion of said seal cap body; and, a second terminal end (616A,618A) conductively accessible from along said second end surface portion of said seal cap body; said first and second terminal ends (616B;618B,616A;618A) adapted for conductive coupling with an associated electrical connector (DPC;GDC;SDC); and, each of said first and second electrical conductors (616,618) including a substantially air-impermeable portion having a substantially fluid-tight connection with said seal cap body with said substantially air-impermeable portion of each of said first and second electrical conductors (616,618) substantially inhibiting fluid communication across said seal cap body through a respective one of said first and second electrical conductors (616,618). a seal cap body having a longitudinal axis and extending radially outward from along said longitudinal axis, said seal cap body at least partially formed from a substantially nonelectrically conductive material and including: a first end surface portion disposed along a first side of said gas spring seal cap (600A;600B;600C;600D); a second end surface portion disposed along a second side of said gas spring seal cap (600A;600B;600C;600D) that is spaced longitudinally from said first side and facing opposite said first end surface portion; and, an outer peripheral surface portion disposed between said first and second end surface portions (614,612); and, a first end surface portion disposed along a first side of said gas spring seal cap (600A;600B;600C;600D); a second end surface portion disposed along a second side of said gas spring seal cap (600A;600B;600C;600D) that is spaced longitudinally from said first side and facing opposite said first end surface portion; and, an outer peripheral surface portion disposed between said first and second end surface portions (614,612); and, a first electrical conductor and a second electrical conductor extending through said seal cap body, each of said first and second electrical conductors (616,618) formed substantially of electrically conductive material directly embedded within said seal cap body without permitting conductive cross-communication between said first and second electrical conductors (616,618) through said substantially nonelectrically conductive material, each of said first and second electrical conductors (616,618) disposed radially inward from said outer peripheral surface portion and including: a first terminal end (616B,618B) conductively accessible from along said first end surface portion of said seal cap body; and, a second terminal end (616A,618A) conductively accessible from along said second end surface portion of said seal cap body; said first and second terminal ends (616B;618B,616A;618A) adapted for conductive coupling with an associated electrical connector (DPC;GDC;SDC); and, each of said first and second electrical conductors (616,618) including a substantially air-impermeable portion having a substantially fluid-tight connection with said seal cap body with said substantially air-impermeable portion of each of said first and second electrical conductors (616,618) substantially inhibiting fluid communication across said seal cap body through a respective one of said first and second electrical conductors (616,618). a first terminal end (616B,618B) conductively accessible from along said first end surface portion of said seal cap body; and, a second terminal end (616A,618A) conductively accessible from along said second end surface portion of said seal cap body; said first and second terminal ends (616B;618B,616A;618A) adapted for conductive coupling with an associated electrical connector (DPC;GDC;SDC); and, each of said first and second electrical conductors (616,618) including a substantially air-impermeable portion having a substantially fluid-tight connection with said seal cap body with said substantially air-impermeable portion of each of said first and second electrical conductors (616,618) substantially inhibiting fluid communication across said seal cap body through a respective one of said first and second electrical conductors (616,618).
