A perforating gun assembly may include a first housing extending along a longitudinal axis and a tandem seal adapter (TSA). The first housing may include a coupling provided at a first end of the first housing. The TSA may include a TSA body and a seal element provided on an outer surface of the TSA body. At least part of the TSA may be positioned inside the first housing such that the seal element and the coupling intersect with a common plane that is perpendicular to the longitudinal axis.
