Broad incumbents

• Watts Water Technologies: US-listed manufacturer of flow-control products including valves, regulators, and safety devices for water, gas, and plumbing. Comparable product technology but operates at much larger scale across plumbing/HVAC rather than LPG specialization.
• Honeywell International: Global industrial conglomerate whose Process Solutions and gas-equipment portfolios include pressure regulators, safety valves, and burner controls. Competes in adjacent industrial gas regulation rather than GOK's residential/recreational LPG niche.
• Emerson Electric (Fisher Controls): Major supplier of process control valves, regulators, and instrumentation via Fisher and other brands. Overlaps with GOK in pressure regulation and gas-system safety, but at much larger scale across oil & gas, chemical, and power end markets.

• GSR Ventiltechnik: German manufacturer of solenoid and control valves for gas, water, and steam. Comparable German SME specializing in safety-critical valves for gas systems with overlapping industrial and commercial LPG customers.
• Marshall Excelsior Company: US manufacturer of LPG and propane valves, regulators, and fittings for gas distribution and recreation. Closely comparable in product scope (regulators, changeover valves, couplings) to GOK's LPG systems portfolio.
• Cavagna Group: Italian-headquartered global manufacturer of LPG regulators, valves, and cylinder equipment. Most directly comparable competitor to GOK in LPG pressure regulation, safety valves, and tank accessories for residential, industrial, and recreational applications.
• Alde International (Truma subsidiary): Swedish maker of caravan and motorhome heating systems including LPG-fired hot water and space heaters. Directly comparable in the leisure-vehicle gas heating and water heating segment where GOK's Caramatic regulators are integrated.
• Dometic Group: Swedish-listed supplier of comfort and safety systems for caravans, motorhomes, marine, and commercial vehicles. Directly competes in LPG/electrical systems for recreational vehicles and adjacent to GOK's leisure and marine sub-brands.
