Stainless Products Inc. SP160-7-2.5-2V O-Ring

Stainless Products Inc. SP160-7-2.5-2V O-Ring is a Viton (FKM) stem seal designed for SPI SP160 short‑stroke valve assemblies. This O‑ring serves as the upper stem seal on SP160‑7 configurations, providing a dedicated Viton material seal for the stem interface where the actuator engages the valve body. The SP160‑7‑2V designation identifies the SP160 family, the 7 size variant, and the Viton compound (2V) used for the seal. SPI catalogs call out Viton stem O‑rings for SP160 valve spare parts, aligning this part with other SP160 stem seals used in stainless‑steel valve bodies. As a Viton O‑ring, it is selected for compatibility with aggressive fluids encountered in SP160 valve service, ensuring reliable leak prevention during operation and service intervals. This part is intended for maintenance and replacement as part of SPI SP160 valve service kits, helping restore stem sealing integrity in stainless‑steel SP160 actuators and accessories.
