Oetiker’s 1-Ear Stainless Stepless clamp closes in a single pincer stroke, locks shut with a mechanical interlock instead of a spot weld, and stays sealed at full pressure year after year — even on poly pipe sitting in wet soil. The 1″ size (part 15500220, Ref. 331) is designed to clamp over a 1″ poly-pipe-on-barb connection, with a closing range of 30.0–32.2 mm (1.181–1.268 in) to handle the OD spread you get from real-world pipe and barb tolerance.\u003c\/p\u003e\u003ch3\u003eWhy Pros Pick Oetiker Over the Cheap Worm-Drive\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMechanical interlock closure — no spot weld, no corroded fail point, no surprise gap opening up in year three\u003c\/li\u003e\n\u003cli\u003eStainless steel band (1.4301 \/ UNS S30400) — ≥ 1000 hours salt-spray corrosion resistance (DIN EN ISO 9227), built to live underground or in wet valve boxes\u003c\/li\u003e\n\u003cli\u003eSingle-stroke tool closure — one squeeze on the pincer and you’re done, no secondary crimping\u003c\/li\u003e\n\u003cli\u003eVisible ear deformation — you can SEE that the clamp closed correctly, no guesswork\u003c\/li\u003e\n\u003cli\u003eRaised dimple in the band — increases radial clamping force without extra band thickness\u003c\/li\u003e\n\u003cli\u003eBurr-free band edges — won’t cut into soft poly pipe over time\u003c\/li\u003e\n\u003cli\u003eToolFit Technology — the ear ships pre-crimped at the factory so the pincer seats squarely and doesn’t slip during the squeeze\u003c\/li\u003e\n\u003cli\u003eMade in USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy ToolFit Matters\u003c\/h3\u003e\u003cp\u003eOn a standard 1-ear clamp, the ear has roughly a 5.6° angle when you reach for it — that’s tight, and the pincer jaws can slip off-center if you’re working in a trench at an awkward angle. The ToolFit ear is pre-crimped to 18° at the factory, giving the pincer a wider, deeper seat. The result: fewer botched crimps, fewer comebacks, faster install on long runs.\u003c\/p\u003e\u003ch3\u003eWhere It Shines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDrip and emitter line connections on 1″ poly distribution mains\u003c\/li\u003e\n\u003cli\u003eService-call replacements on failed worm-drive or import ear clamps\u003c\/li\u003e\n\u003cli\u003eLow-voltage \/ outdoor environments where a stainless band outlasts a zinc or plated steel clamp by 5+ years\u003c\/li\u003e\n\u003cli\u003eAny irrigation install in the rust belt or coastal zones where corrosion is the #1 callback cause\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part: \u003cstrong\u003e15500220\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eOetiker Reference: 331\u003c\/li\u003e\n\u003cli\u003eSeries: PG 155 (Stainless Steel)\u003c\/li\u003e\n\u003cli\u003eBand material: Stainless Steel 1.4301 \/ UNS S30400\u003c\/li\u003e\n\u003cli\u003eTube size designation: \u003cstrong\u003e1 in nominal\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eClosing diameter range: 30.0 mm to 32.2 mm (1.181 in to 1.268 in)\u003c\/li\u003e\n\u003cli\u003eBand width: 7.0 mm (0.276 in)\u003c\/li\u003e\n\u003cli\u003eBand thickness: 0.6 \/ 0.8 mm\u003c\/li\u003e\n\u003cli\u003eEar width inside: 10 mm\u003c\/li\u003e\n\u003cli\u003eClosure: Mechanical interlock (not spot-welded)\u003c\/li\u003e\n\u003cli\u003eEar style: ToolFit pre-crimped (18° factory crimp angle)\u003c\/li\u003e\n\u003cli\u003eClosing force (max): 2000 N\u003c\/li\u003e\n\u003cli\u003eCorrosion resistance: ≥ 1000 hours (DIN EN ISO 9227, salt spray)\u003c\/li\u003e\n\u003cli\u003eReusable: No — cut off and replace after removal\u003c\/li\u003e\n\u003cli\u003eOrigin: Made in USA\u003c\/li\u003e\n\u003cli\u003eApproximate weight: Listed at 1 lb pack (per Garoppo’s pricing unit)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Closing Tools\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManual:\u003c\/strong\u003e Oetiker HMK 01 or S01 pincers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePneumatic:\u003c\/strong\u003e Oetiker HO ME 2000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCordless:\u003c\/strong\u003e Oetiker CP 01\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Close in a single tool stroke.
