SAFETY INFORMATION

Never attempt to tighten (or loosen) fittings that are under pressure. Always assume a leak is caused by more than an under-tightened fitting and fully investigate

Fitting Disconnection and Reconnection:

• Before discontinuing, mark the fitting body and nut.
• Ensure all pressure is purged from the system.
• Loosen the fitting nut a few turns but do not remove nut from body, tap or shake tub, checking for gas release.
• Disconnect fitting (only once system is purged and no gas release after check).
• Prior to reconnection ensure all sealing surfaces and thread forms are free from contamination and that thread forms are checked for damage.
• A check should also be made for tube insertion depth, to ensure that he tube had been correctly inserted upon initial make up, this can be done using a gauge.

SBT Joints are Vulnerable Due to:

• Joints under-tightened / over-tightened
• Mixing of non-compatible or dissimilar fittings (imperial/metric, different materials & manufactures)
• Cut ends of poor quality (not straight/too rough)
• Incorrect thread sealants & lubricants (tapes, liquid)
• Joints made too close to bends (poorer seal & stress raisers)
• Damaged or not re-made properly after maintenance, venting, purging, leak testing, positive isolation activities
• Vibration damage
