Descriptions of Service

All cleaning is suitable for oxygen service. We use only oxygen-compatible O-rings and lubricants during all maintenance. for more information about oxygen service.

Buoyancy Compensator (BCD). Recommended annually. Turnaround time is normally two days.
    Completely disassemble, clean, and carefully inspect all parts for damage/corrosion/wear.
    Replace any parts as appropriate.
    Reassemble and test.

Cylinder, interior inspection. Required anytime there is concern about possible internal contamination of the cylinder or when the cylinder is leaking at the neck/valve O-ring. Turnaround time is normally immediate.
    Remove the valve, and perform a lighted inspection of the cylinder interior.
    Clean the neck/valve threads, lubricate and install new neck/valve O-ring.
    Install valve on cylinder, and test for leaks.
    Does NOT include fill.

Cylinder, full Visual Inspection. Required annually. Turnaround time is normally next day; however, same day service is available upon request at no additional charge. Eddy current exam is required for aluminum 6351 alloy cylinders, and suggested for all aluminum cylinders. for more information about eddy current exams.
    Inspect to standards of Professional Scuba Inspectors, Inc. (PSI)
    If appropriate, use an eddy current device to further evaluate the threads.
    Clean the neck/valve threads, lubricate and install new neck/valve O-ring.
    Install valve on cylinder, and test for leaks.
    Supply full documentation of inspection.

Benthic SCUBA does not recommend renewing the visual inspection or hydro-static test for aluminum 6351-T6 alloy SCUBA cylinders because of problems with sustained load cracking (SLC) in those cylinders. We recommend that aluminum 6351-T6 SCUBA cylinders be removed from service. Luxfer, who manufactured the overwhelming majority of aluminum 6351-T6 cylinders between 1977 and 1988, has announced an exchange program for those cylinders that runs throughout the 2003 calendar year. Owners can return 6351-T6 alloy SCUBA cylinders to Luxfer in exchange for a $50-per-cylinder credit against the purchase of a new Luxfer SCUBA cylinder. Benthic SCUBA suggests that owners of 6351-T6 alloy SCUBA cylinders take advantage of Luxfer's exchange program. Which Cylinders Were Made From 6351-T6 Aluminum? All DOT-3AL tanks manufactured under one of the following exemptions or special permits: 6498, 7042, 8107, 8364, 8422 All Walter Kidde DOT-3AL scuba tanks. All Cliff Impact DOT-3AL scuba tanks made before July 1990. All Luxfer 80.8 cu. ft. scuba tanks (S80.8) made before May 1987. All Luxfer scuba tanks made before August 1987. All other scuba tanks made in the US before February 1990 (except Catalina). All scuba tanks not made in the US. Which cylinders cannot be hydrostatically tested? Cylinders manufactured after 1993 that DO NOT have a TC (Transport Canada) approval embossed into the crown of the cylinder can NOT be tested. The cylinder is effectively defunct. The cylinder must be removed from service.

Cylinder, hydrostatic test. Required every five years. Turnaround time is two days, and we offer priority rush service. This service is normally combined with a separately priced full visual inspection.
    Test the cylinder at a TC-authorized hydrostatic test facility.
    Rinse cylinder interior and throughly dry.

Cylinder, tumble and clean interior. Required when significant interior corrosion is present. Turnaround time is next day. This service is normally combined with a separately priced full visual inspection.
    Dry tumble cylinder with abrasive appropriate for cylinder composition.
    Blow out cylinder with high pressure air to remove all dust.

Cylinder, shot blast exterior. Recommended when existing coating is promoting corrosion. Suggested when external appearance of cylinder is unsatisfactory. Turnaround time is four days, and we offer priority rush service. This service is normally combined with a separately priced full visual inspection.
    Completely strip paint from cylinder.
    Refinish with shot blast texture.

Cylinder and Valve, prepare for oxygen service. Turnaround time is next day. This service is normally combined with a separately priced full visual inspection.
    Wash cylinder interior with environmentally safe detergents to remove hydrocarbon contamination.
    Rinse cylinder interior and throughly dry.
    Completely disassemble valve, hydrostatically clean, and carefully inspect all parts for damage/corrosion/wear.
    Replace any parts as appropriate, and always replace the burst disk and all O-rings using oxygen-compatible products.

Octopus, periodic maintenance. Recommended annually. Turnaround time is two days, and we offer priority rush service.
    Maintain 1st and 2nd stage, additional second stage, SPG, and BCD hose end.
    Completely disassemble, hydrostatically clean, and carefully inspect all parts for damage/corrosion/wear.
    Replace any parts as appropriate, and always replace all soft parts and seats.
    Assemble, test, and tune to factory specifications.
    Check the submersible pressure gauge for accuracy across a range of pressures.
    Inspect the high-pressure swivel, and replace O-rings.
    Inspect all hoses, clean and lubricate the BCD hose end.

Regulator, periodic maintenance. Recommended annually. Turnaround time is two days, and we offer priority rush service.
    Similar to the octopus maintenance but only for the regulator 1st stage, 2nd stage, and hose.

Valve, periodic maintenance. Recommended at same time as cylinder hydrostatic test. Turnaround time is next day.
    Completely disassemble, ultrasonical clean, and carefully inspect all parts for damage/corrosion/wear.
    Replace any parts as appropriate, and always replace the burst disk and all O-rings.
