Discussion Overview

The discussion revolves around methods for separating a rubber-ended hose from a gas regulator or connector, focusing on practical tips and techniques for achieving this without damaging the components involved.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks advice on separating a rubber-ended hose from a gas regulator, emphasizing the need to avoid damage.
  • Another participant explains that a hose barb allows for a tight fit due to the contraction of the rubber hose when pulled, suggesting the use of thin blades to help remove the hose by allowing it to expand.
  • Heating the rubber with boiling water is proposed as a method to soften it for easier removal.
  • A different viewpoint raises concerns about the safety and recommendations regarding disconnection of gas pipes, suggesting that destructive methods are preferred to prevent reconnection.
  • Links to external tools designed for hose removal are provided as additional resources.

Areas of Agreement / Disagreement

Participants express differing views on the safety and recommended practices for disconnecting gas hoses, with some advocating for careful disconnection methods while others suggest more cautious approaches involving destruction of the connection.

Contextual Notes

There are unresolved concerns regarding local regulations and safety recommendations for handling gas pipes, which may influence the methods discussed.

TL;DR
Definitive and correct way to apart/separate a rubber-ended hose with the gas regulator/connector
Anyone outright experience or understand tips and tricks to apart/separate a rubber-ended hose with the gas regulator/connector (as the right pipe mouth below but sorry no rubber-end hose pic) ?

It indeed so hard
so any clear idea, with keep everything intact unbroken on mind, how to do and by help of which suitable liquid ?

The serrated fitting on the RHS is called a hose barb. You can push a rubber hose onto the barb, because a hose expands when under axial compression. When you pull the hose to remove it, the hose contracts onto the barb and holds on tight.

To remove a hose from a barb, use a couple of thin blades to press against the cut end of the rubber hose. You can then push the hose off because the hose will expand under axial compression.

If the rubber is hard, you can heat it with boiling water to soften it.

If the rubber is bonded to the barb, hold the rubber on the barb with pliers, then rotate the rubber tube on the barb to break the bond.

I don't know the relevant local recommendations and regulations, but here this kind of disconnection is not recommended any more for gas pipes. If the pipe is to be removed then destructive methods are preferred, so it could not be reconnected again: when a new connection is to be made, then all fresh is the way.
And if it's about appliances, then all new and factory made.

Yeah, I do know that if done with care it works. We did it that way back too. Just adding my piece.
