WHAT YOU NEED TO KNOW
PTFE tape on tapered threads (NPT/BSPT) JIC/AN flare connections seal metal-to-metal — no tape
NPT != BSPT — look identical, NOT interchangeable
PRODUCT OVERVIEW

Note: Cables with IEC C13 sockets such as this are sometimes known by the generic term 'kettle lead'. Even though this term is commonly used, technically it is incorrect as a kettle requires special IEC C15/16 connectors rated at 120 degrees. So, although they look similar, a 'real' kettle lead features a connector with a cut out on the top.

Standard IEC C13 cables cannot be plugged into kettles! This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 4730-00-289-0368, indicating validated use in U.S. government and defense logistics supply chains.

HOSE FITTING — THREAD TYPE IS CRITICAL END A: — STRAIGHT END B: — SPECIFICATIONS Thread: — Material: — Pressure: — PN: 304 3-8 · Lindy ⚠ VERIFY BEFORE ORDERING NPT ≠ BSPT — tapered threads look identical but are NOT interchangeable. Wrong thread = leak. JIC (37°) ≠ AN (37°) ≠ SAE 45° — flare angles must match exactly. Measure thread pitch with gauge — visual identification is unreliable ✓ BROKER TIP Always use thread sealant (PTFE tape or pipe compound) on tapered threads (NPT/BSPT). JIC/AN flare fittings seal metal-to-metal — never use tape on flare connections PARTSTABLE TECHNICAL DRAWING — NOT TO SCALE
