What is the standard warranty period for HYSF products?

HYSF provides a standard 12-month warranty from the date of shipment for all connectors and subsea equipment. This warranty covers defects in materials and workmanship. For specific military or deep-sea projects, extended warranty options may be negotiated.

We stand behind the quality of our manufacturing.

  • Coverage: The warranty covers any failure caused by manufacturing defects (e.g., poor vulcanization, material flaws) under normal use.
  • Resolution: In the unlikely event of a failure, we offer repair or replacement services.
  • Exclusions: As per industry standard, the warranty does not cover damage caused by improper installation (e.g., over-torquing), misuse (e.g., exceeding depth ratings), or normal wear and tear of consumable parts like O-rings.
  • Confidence: Our 99.98% reliability rate means warranty claims are extremely rare.
