OPW 66SP High-Volume Breakaways

The 66SP is designed for installation on fuel dispensing hoses that require a substantial volume of flow, and therefore the potential for a high-volume spill.

The 66SP utilizes shear pin technology to ensure separation at proper pull forces, and limit unwanted valve closures that stop or limit fuel flow. Once separated, a qualified service technician can easily repair the breakaway with an OPW 66PRK Shear Pin Replacement Kit.

  • Pull Force – the 66SP will separate with a maximum pull force of 600 lbs., and limits fuel spillage from either hose end.
  • Easily Repaired – after separation, the 66SP can be repaired and put back in service with the OPW 66PRK Shear Pin Replacement Kit.
  • Heavy-Duty Construction – physically designed for durability in high-volume environments, including a protective, red, anodized-aluminum body.
  • Low Pressure Drop – valve design ensures superior flow rate for high-volume fills.
  • Special Seals – special fluorosilicone (66SP-5200 only) O-Rings help protect the valve in harsh, high-volume environments.
