Buying gas stove parts without inspecting them is a gamble. A defect that slips through on nozzles or burner caps becomes returns, unhappy customers, and lost margin. A simple quality inspection — done before you commit or on arrival — protects your business. Here is the checklist.
The first thing to verify is dimension. Measure the burner cap outer diameter (#130 = 130mm, #100 = 100mm, #75 = 75mm, #55 = 55mm) and the nozzle aperture with a pin gauge. A part that is a millimeter off will not fit the stove — dimension is the most common source of returns.
Nozzles must match the unified M6x0.75 thread. Check that the thread is clean, well-formed, and seats properly. A loose or cross-threaded nozzle is a gas-leak risk, not just a fit problem.
Inspect the surface finish — glossy flat, glossy concave, or matte flat — against your order. Look for chips, uneven enamel, or discoloration. A consistent finish is what your customers expect, and inconsistency signals poor manufacturing control.
Confirm the material matches your order — brass nozzles, pressed steel or cast burner caps, aluminum flame spreaders. Check for sharp edges, cracks, or weak points that would fail in use.
Before a large order, request samples and inspect them against this checklist. Only scale up once the samples pass. THREEMI supports pre-shipment inspection and third-party inspection on request, so you can buy with confidence.
