Abstract: An annular seal including a body defining a central lumen and a weakened portion disposed around the central lumen. In an embodiment, the weakened portion includes at least one aperture or a plurality of apertures. In a further embodiment, the apertures may be identical to one another. An annular seal including a body defining a central lumen bounded by a sidewall, wherein the body has a dual-elastic modulus profile including a first elastic modulus, S1, as measured along the sidewall prior to assembly with an inner component, and a second elastic modulus, S2, as measured along the sidewall after assembly with the inner component, and wherein the first elastic modulus is less than the second elastic modulus.

Abstract: A stem packing assembly including a first annular member defining a central axis, a second annular member defining a central axis coaxial with the central axis of the first annular member, and an annular energizing member defining a central axis coaxial with the central axis of the first annular member. In an embodiment, the stem packing assembly can have a leakage rate according to ISO 15848-1 of less than 1×10−4 mgs−1m−1 for at least 500 cycles at 160° C., and less than 1×10−4 mgs−1m−1 for at least 500 cycles at −46° C. In another embodiment, the first annular member can include a PAEK, the second annular member can include a PTFE, and the annular energizing member at least partially includes a PTFE.
