Quality Assurance

A. Warranty period:
This Warranty covers all aluminum and composite cylinders and steel cylinders for 15 years from the original hydrostatic test date on each cylinder. (On an aluminum and steel cylinder, the original hydrostatic test date is the earliest test date stamped on the cylinder crown. On a composite cylinder, the original hydrostatic test date is the earliest test date either stamped on the cylinder neck or printed on a label on the cylinder body.)

B. Warranty covers:
1. JC Gas Cylinders warrants that each new aluminum or composite or steel cylinder will be free of manufacturing and workmanship defects.
2. We warrant the external and internal cleanliness of each cylinder, which will be judged in accordance with applicable regulations and with international quality standards, which meet or exceed all relevant requirements.
3. On a painted or powder-coated cylinder,JC Gas Cylinders warrants that the initial exterior finish of the cylinder will be free of defects when the cylinder leaves the factory.

C. Restrictions:
1. Throughout the entire 15-year warranty period, the cylinder must be visually inspected internally and externally by properly trained and certified inspectors at intervals required by applicable regulations. The results of each required inspection must be properly documented in accordance with applicable regulations. The cylinder must not be filled or pressurized beyond its rated working capacity. Overfilling or overpressurizing the cylinder will immediately void this warranty.
2. The cylinder must be used only for the specific purpose or service for which it was designed.
(For example, medical oxygen cylinders must not be used for scuba diving.) Using a JC cylinder for a purpose or service for which it was not designed will immediately void this warranty.
3. JC reserves the right to retest or reinspect any cylinder returned with the claim that it has failed any type of test or inspection (including but not limited to required periodic requalification testing, hydrostatic retesting, ultrasonic testing, eddy-current testing and/or visual inspection). JC further reserves the right to make the final determination concerning proper disposition of any returned cylinder; disposition will be made in accordance with all applicable regulations at the time of inspection.
4. This non-transferable warranty is valid only for the original owner of each JC cylinder. Proper documentation of ownership, such as a valid warranty card and/or an original purchase receipt, will be required to verify original ownership before any warranty claims will be honored.
5. Cylinders will be replaced only in accordance with current, published JUNCHEEC policy. JUNCHEE reserves the right to change policies, including provisions of this Warranty, without prior notice.

D. What this Warranty does not cover:
1. Cylinders damaged during shipping and handling, including damage to exterior finishes.
2. Cosmetic damages, including scratches, dents, nicks and abrasions that occur after a new cylinder is removed from its packaging for the first time.
3. Cylinders involved in accidents and fires.
4. Cylinder damages, including corrosion, resulting from improper use, improper storage, improper maintenance and/or negligence.
5. The performance of paints, coatings and finishes.JUNCHEE offers no warranties for coatings products other than those provided by the manufacturers of such products.
6. Cylinders subjected to unauthorized repairs and modifications, including (but not limited to) grinding, cutting, sand-blasting, shot-blasting, media-blasting, sanding, brushing, polishing, engraving, scraping and any other activity that removes metal and thins cylinder walls on aluminum cylinders or affects the epoxy resin matrix or protective fiber overwrap on composite cylinders. Additional unauthorized activities include subjecting cylinders to various harsh chemicals (e.g., certain cleaners, caustics, acids, solvents, coatings and other corrosive substances); exposing cylinders to heat processes that could anneal aluminum or adversely affect epoxy resin and fibers; recutting or resurfacing O-ring glands; and rethreading cylinders. Such unauthorized activities will immediately void this Warranty. Moreover, since cylinders modified or affected by such unauthorized activities may become unsafe to fill and use, JUNCHEE accepts no responsibility or liability for the condition or performance of any JC cylinder modified by unauthorized persons or companies.
