Notification
 Valve fittings for LPG cylinders of more than 5 litre capacity, covered under IS 8737 (Part 2), are regulated under the Gas Cylinders Rules, 2016, notified by GSR 1081(E) dated 22 November 2016. The Rules superseded the 2004 framework, were first published as draft GSR 779(E) dated 13 October 2015, and were amended later through the Gas Cylinders (Amendment) Rules, 2022.
Enforcement Timeline
 The provisions of the Gas Cylinders Rules, 2016 became enforceable on 22 November 2016, making PESO approval and compliance with IS 8737 mandatory from that date.
Overview
 IS 8737 specifies requirements for valve fittings for newly manufactured LPG cylinders of more than 5 litre water capacity. These fittings are critical safety components, ensuring leak-tightness, controlled gas release, and interchangeability in domestic, commercial, and industrial LPG applications.
Objective & Scope
 The objective is to ensure that valve fittings used in LPG cylinders are safe, standardised, and compatible with national safety norms, thereby reducing risks of leaks, fire, and explosion during filling, transportation, storage, and usage.
Products Covered
 Applies to valve fittings for LPG cylinders > 5 litre, intended for household, commercial, and industrial LPG distribution systems.
Exemptions Provided
 No product-specific exemptions exist. Only limited exemptions under Rule 44 of GCR 2016 (e.g., for possession of small numbers of cylinders for own use without licence) may apply.
Industries Impacted
 This requirement affects LPG cylinder and valve manufacturers, OMCs, LPG bottling and distribution plants, PESO-approved testing stations, and downstream distributors.
Mandatory Compliance Requirements
 Valve fittings must conform to IS 8737 (Part 2), be type-tested and design-approved by PESO, and carry proper stamping and identification. They must be used in conjunction with compliant LPG cylinders (IS 3196) and associated valve assemblies/regulators.
Next Steps for Stakeholders
 Manufacturers and bottling plants must obtain PESO approval for valve fitting designs, implement production in line with IS 8737 (Scheme-I ) , ensure correct stamping and marking, and maintain traceability and documentation as required under GCR 2016.
Legal Provisions, Enforcement & Penalties
 Enforced under the Explosives Act, 1884 and Gas Cylinders Rules, 2016, PESO is empowered to inspect, seize non-compliant valves, suspend approvals, and initiate prosecution. Penalties include fines, cancellation of approvals, and imprisonment.
Conclusion
 IS 8737 (Part 2) valve fittings for newly manufactured LPG cylinders above 5 litre capacity are strictly regulated under GCR 2016. PESO approval, IS compliance, stamping, and record-keeping are mandatory to ensure safe use in LPG distribution.
