304 Stainless Steel Oxygen Sensor Adapter with Catalyst

This oxygen sensor adapter combines a silver-coloured stainless-steel body with a three-way catalyst insert in the confirmed Catalyst configuration. It is a mechanical threaded adapter, not an electronic oxygen sensor or a replacement wiring connector. For shoppers comparing exhaust-related components, the useful starting points are the documented material, the visible threaded construction, and the measurements shown in the original product diagram. Match those details to your intended application before ordering rather than relying on the supplier's broad general-application wording.

Key Features

• Confirmed configuration: 304 stainless steel with a three-way catalyst.
• Threaded adapter body with a hexagonal end, as shown in the product photographs.
• Original dimension diagram specifies a length of 57 mm, also labelled 2.2 inches.
• Internal thread is labelled M18 × 1.5 in the original diagram.
• One piece supplied in the selected Catalyst configuration.

The photographs show the body from several angles, along with a view of the catalyst insert. These are helpful visual references for understanding the component's shape, but a photograph alone cannot establish compatibility with a particular vehicle. Check the available space, matching connections, and required specifications with a qualified automotive professional before selecting an adapter.

Who This Is For

• Shoppers looking specifically for a mechanical oxygen sensor adapter with a catalyst insert.
• Owners comparing documented component dimensions before discussing fitment with a technician.
• Buyers who have already identified the required connection and confirmed that this configuration suits their application.

If you are shopping because a warning light has appeared, this listing does not establish the cause of that warning. No diagnostic result, fault-code resolution, emissions performance, or vehicle-specific fitment is guaranteed here. The adapter should not be confused with a replacement sensor, a complete catalytic converter, or a diagnosis of an existing exhaust-system problem. Identify the part you actually need before making a purchasing decision.

Product Details

The sold option is named Catalyst. Its material and insert specification are 304 stainless steel with a three-way catalyst, as confirmed for this listing. An original gallery photograph also carries a 201 stainless-steel label; that photograph is retained for reference and does not describe the confirmed sold configuration. Use the written configuration below when comparing this item, and ask for clarification if the pictured alternatives create uncertainty.

The thread specification above is explicitly the internal thread shown in the source image. An external thread specification, installation torque, vehicle model list, and application-specific clearance requirement are not supplied in the verified product details. Do not assume that one matching measurement confirms the complete installation. The original packing text calls the item “Sensor x1pc”; the photographs and selected option identify the listed component as the adapter shown, rather than an electronic sensing assembly.

FAQ

Is this an oxygen sensor?

No. The item shown is a threaded mechanical oxygen sensor adapter with a catalyst insert. It is not an electronic oxygen sensor, a wiring harness, or a complete catalytic converter. Review the component photos carefully so you are ordering the intended type of part.

Which material is supplied?

The confirmed Catalyst configuration is 304 stainless steel with a three-way catalyst. A retained original photograph is labelled 201 stainless steel, but that alternative label does not represent the confirmed material of the sold option.

What measurements are documented?

The original diagram labels the length as 57 mm / 2.2 inches and the internal thread as M18 × 1.5. The table reproduces those source labels rather than adding inferred dimensions. Use the diagram alongside an application-specific fitment check.

Will it fit every vehicle or resolve a warning light?

No universal-fit or warning-light-resolution guarantee is made. The original general-application wording is not a vehicle compatibility list. Have the underlying issue and required component specifications checked before purchasing; the listing alone cannot confirm an installation or repair outcome.

What is included and what if it is unsuitable?

The listed package quantity is one piece in the Catalyst configuration. EX-STOCK Canada offers a 90-day return policy; contact support within 90 days of delivery to discuss a return or exchange. Items must be in original, unused condition, and return shipping costs may apply.
