Good morning, thank you for taking the time to leave us a review, sorry to hear the tabs on the fittings received were sharp - definitely not what we like to hear! We have passed your feedback onto our product team and will get them to double check stock we have in the warehouse to ensure this is not a common issue. If you require replacement fittings due to this, please let us know. More than happy to organise these for you if needed. Kind regards, The Hoselink Team
