Sta-Plug® Emergency Plug - The Emergency Plug that Grips™


Sta-Plug® is Forespar’s form fitting emergency plug.  A soft cone shaped design allows it to easily fill the irregular shapes of hull impact breaches, as well as any round hole leak from a hose or through-hull.  Unique edge gripping riblets help hold the plug in a hole, keeping water out.  The riblets help Sta-Plug® conform to the shape of the hole, sealing a leak near the edge where a tight fit is crucial, and holding the plug more securely in place. Different by design, Sta-Plug’s® shape includes a series of concentrically larger riblets stepped along the length of the cone.  These riblets offer two big advantages over traditional straight edged emergency plugs:

  • They help Sta-Plug® conform to the hole near the edge where a tight fit is most crucial.
  • They help hold it more securely in place.
  • Twist and compress by hand to insert into hole.
  • Expands after insertion to hold in place.


Intended for temporary emergency use with continuous monitoring only, it gives the skipper greater peace-of-mind to allow them to focus on getting the boat to safety.

Made from high density foam, Sta-Plug® will remain soft and ready to go for years and will not mold or swell up like conventional wood plugs.

  • Can be cut with a knife to use in irregular shaped holes, or torn by hand near the riblets to make smaller diameter plugs for smaller holes.  Tearing at the 8th riblet creates a plug with a 2” diameter base.
  • Made from high density foam that is not susceptible to mold or swelling.
  • Bright orange color allows it to be quickly located in an emergency.
  • Dimensions:  9” High x 5” Diameter at base
  • Made right here in the USA.
  • Installation Video

Sta-Plug is also great for non-marine applications. In your RV/vehicle, home, workplace, and elsewhere. Customers have used it for leak control and temporary repair of low-pressure storage tanks, drums, and other containers.

  • Quick repair of storage tanks.
  • Ideal for emergency leak repairs on all types of metal, plastic, or composite tanks, drums, and shells.
  • Quickly stop leaks in low-pressure stainless steel/plastic containers.
  • Ideal for patching and repairing steel or plastic drums.
  • Will slow but may not completely stop leaks. Not for use with fuel leaks.

For temporary leak control only until appropriate disposal of the container, or permanent repair is possible.
