  • PHYSICAL PROPERTIES

    SPS Line

    Same Fit. Lasting Reliability.

    Our SPS single-spring seals are like-for-like replacements for industry-standard “E” / “1” types—delivering the same fit and function with upgraded construction for longer service life.

    What sets SPS apart

    • Heavier elastomer bellows for added strength and stability under load

    • Resin-impregnated, double-density carbon faces for enhanced hardness and wear resistance

    • 316 stainless steel metal components on E/1 heads for superior corrosion resistance

    • Precision-machined head finish for consistent compression and sealing performance

    Engineered to rigorous standards, SPS seals provide a durable, dependable alternative to common aftermarket or OEM options—compare them against your current line and see the difference.
