The kit includes a 304 stainless bracket, fasteners, crush washers, flanges, an exhaust gasket and a removable spacer adapter with a universal M18 x 1.5 female thread that fits most wideband sensors. Designed for simplicity and corrosion resistance, the no-weld design reduces shop time and preserves the original exhaust tubing.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the clamp-on design simplify adding a wideband sensor?\u003c\/h3\u003e\n\u003cp\u003eInstead of cutting and welding in a permanent bung, this clamp-on adapter wraps around the exhaust pipe and secures the sensor port in place.

It’s ideal when testing sensor placement, adding an auxiliary wideband for tuning, or fitting a replacement sensor where factory bungs are absent or inaccessible. If you need a durable, corrosion-resistant adapter with a standard M18 thread and a no-weld install, this kit provides the components and hardware to get the job done cleanly.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this adapter require welding?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the HEBRAR kit clamps onto the pipe and installs without welding.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What thread size fits the sensor?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It uses a standard M18 x 1.5 female thread compatible with most wideband sensors.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"HEBRAR","offers":[{"title":"Default Title","offer_id":67591530119353,"sku":"B0GHR35KZN","price":69.21,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/hebrar-clamp-on-bung-front-view.jpg?v=1790554419","url":"https:\/\/redleafauto.ca\/products\/hebrar-o2-sensor-adapter-clamp-on-for-1-3-4-2-exhaust-pipe-304-stainless-no-weld-kit-m18-x-1-5","provider":"Redleaf Auto","version":"1.0","type":"link"}
