Burner Cap Outer Diameter vs Pan Support Match: Getting the Fit Right

When a burner cap does not fit, the stove looks wrong, cooks unevenly, and rattles. Most fit problems come down to one measurement: the burner cap outer diameter, and how it relates to the pan support and the hob cutout it sits in. For OEM buyers building their own SABAF-compatible stove range, getting this match right is a make-or-break detail.

The Three Measurements That Must Agree

• Burner cap outer diameter — the cap's overall size, measured across its rim.
• Pan support opening — the support the cookware rests on must clear the cap and hold pans level.
• Hob cutout — the opening in the hob plate where the burner assembly mounts.

When all three align, the cap seats flush, the flame spreads evenly, and the cookware sits stable. When any one is off, you get wobble, gaps, or flame impingement that wastes gas and scorches the bottom of pans.

The SABAF-Compatible Size Range

SABAF-compatible burners come in four standard diameters, which gives you a clean design system to build on:

• #130 (No.1) — 130mm outer ring, high-output.
• #100 (No.2) — 100mm, the versatile mid-size.
• #75 (No.3) — 75mm, compact.
• #55 (No.4) — 55mm, small inner ring.

Designing for a Perfect Fit

The key is to design your hob cutout and pan support around the cap diameter you choose, with the correct clearance so the cap seats without binding and the flame spreads without obstruction. Getting this right once — and reusing it across your range — is the whole point of standardizing on the SABAF platform.
