DOT Cylinder Re-qualification Requirements and How to Read the Date Stamps
DOT-specification LP cylinders carry a manufacturing date stamped on the collar in month/year format (e.g., 11/2006 for November 2006). The initial re-qualification requirement is 12 years from manufacture date. After the first re-qualification, the cylinder must be re-qualified every 5 years. Re-qualification stamps are applied by a licensed DOT cylinder re-qualifier and show the qualifier's registration number followed by the re-qualification date. The most recent stamp is the valid reference: if it shows 09/23 (September 2023) with a 5-year interval, the next required re-qualification is 09/2028. A cylinder with no re-qualification stamp at or after the 12-year mark cannot be legally refilled. ASME tanks - the permanently mounted horizontal tanks on many motorhomes - are exempt from DOT re-qualification requirements but are subject to NFPA 58 inspection at the time of filling (valve condition, external corrosion, and OPD presence). Florida's LP filling stations are required by NFPA 58 Section 6.24 to refuse refilling of any cylinder that cannot be positively identified as in-date.
LP Tank Rejection Criteria Beyond Date Stamps - Corrosion, Dents, and Valve Condition
A cylinder within its re-qualification date may still be rejected for physical condition under NFPA 58. Rejection criteria include: external corrosion pitting deeper than 1/32 inch anywhere on the cylinder body; dents over 1/4 inch deep or any dent with sharp creasing (which indicates stress concentration at the crease); fire damage evidenced by paint blistering over more than 4 square inches; bulging or distortion of the cylinder body; and valve damage including a bent valve stem, cracked valve handwheel, or OPD actuator that does not spring back after release. The OPD test is simple: press the actuator lever inward by hand (it is the small lever on the side of the valve under the collar). It should return immediately when released. If it sticks or moves without resistance (float not engaging), the OPD float mechanism has failed and the valve requires replacement before the cylinder can be refilled. Jesse Earl carries OPD valve replacement kits (Worthington OPD valve P/N 200-0150) for POL and ACME 1-inch left-hand thread interfaces.

Case Study: LP Tank Inspection & Replacement Repair
RV: 2018 Grand Design Solitude 379FL • Location: Hillsborough River State Park, Site 33 • City:
Symptom: Campground LP filling station refused to fill the Solitude's 30-lb DOT-7B cylinders; filling attendant cited the date collar showing manufacture date of 11/2006; cylinders were 18 years old with one prior requalification stamp at the 12-year mark (11/2018); no re-qualification stamp after 2018
Diagnosis: Jesse Earl inspected both 30-lb cylinders (Manchester Tank M9430-3 steel construction). Cylinder A: manufacture date 11/2006, requalification stamp 11/2018 (valid at 12 years), no subsequent 5-year requalification stamp - next required requalification was 11/2023, which had passed. Cylinder A showed surface rust on the bottom ring but no pitting. Cylinder B: manufacture date 11/2006, requalification stamp 11/2018, subsequent requalification stamp 09/2023 (within the 5-year window) - still valid until 09/2028. Cylinder A valve showed an OPD (Overfill Prevention Device) actuator that moved freely without resistance, indicating the float mechanism was functional.
Outcome: New cylinder A weighed to verify 30-lb tare weight (stamped TW on collar: 17.2 lbs; scale: 17.4 lbs - within tolerance); OPD valve tested with actuator probe; both cylinders accepted at campground LP station on same afternoon
