Straight Rubber Sleeve Coupling with Stainless Steel Clamps

Description

Straight Rubber Sleeve Coupling with Stainless Steel Clamps

This straight rubber sleeve coupling combines a cylindrical rubber body with clamp-style pipe connections. IKSONIC is a China-based supplier for wholesale buyers comparing sleeve sizes, replacement connections and custom rubber-part requirements. The listing includes 33 dimensional straight-coupling options, two of which specify an iron-sheet jacket. Select the exact version by its dimensions and construction, not by the product photograph alone.

Product Details

• Product form: Straight cylindrical rubber sleeve coupling.
• Clamp description: Stainless steel clamps, as stated in the product title. The stainless grade and tightening specification are not established by the listing.
• Jacketed variants: The 110*130*200 and 160*180*100 options specifically state an iron-sheet jacket. This jacket description must not be replaced with a stainless steel claim.
• Material selection: Promotional material mentions rubber, silicone, EPDM, NBR, natural rubber and fluororubber. This is a general material offering, not a confirmed compound for every option. Confirm the required formulation for your application.
• Custom enquiries: A separate custom-specification enquiry is listed, but it has no defined dimensions or confirmed production terms.

Specifications / Models

33 Listed Straight-Coupling Options

All 33 dimensional option labels are retained below. “Flexible clamp coupling” and “Custom specification enquiry” are non-dimensional placeholders and are excluded from the model count. The first option explicitly states inner diameter, outer diameter, height and mm units. Most other option labels are numeric strings without units; they must not automatically be interpreted as confirmed millimetre dimensions. Exact matching photo references are identified where available.

19 Source-Photo Dimension References

The following table separately transcribes all 19 dimension-labelled photos included in the source listing. Every dimension in this table is explicitly shown in mm. ID means sleeve inner diameter; OD means sleeve outer diameter. For reducer references, a slash separates the dimensions at the two ends, not an adjustment range. Ten references match listed options; nine are photo-only references. The four reducer photos are not listed straight-coupling models and require a separate enquiry.

Preserved dimensional differences: The labels 90*100*90, 75*85*90 and 160*170*150 are retained as listed; photos with the same ID/OD numbers show a height of 100 mm. Options 63*73*63 and 63*73*150 also have no exact photo match: the corresponding diameter photos show heights of 70 mm and 100 mm. Photo 18 shows ID 110 mm, OD 120 mm and height 70 mm, while photo 12 supports the separate 110*120*100 option. Confirm the required height rather than treating these references as interchangeable.

The cleaned dimensional illustration showing ID 63 mm, OD 73 mm and height 70 mm represents only that specification. It is not a universal size diagram for the assortment or the iron-sheet-jacket variants.

Specification Checklist for Buyers

1. Record the actual outside diameter of each pipe end and the required sleeve inner diameter, outer diameter and height, with units.
2. Quote the complete listed option. For an iron-sheet-jacket version, retain that construction description in the enquiry.
3. Describe the medium, temperature, working pressure and installation environment so the required rubber compound and complete assembly can be assessed.
4. Confirm clamp details, pipe engagement, installation instructions and quantity for the selected specification.

No verified pressure rating, service-temperature range, hardness specification or certification for the complete coupling is established here. Generic material charts are not ratings for a particular sleeve-and-clamp assembly.

Frequently Asked Questions

Is the iron-sheet jacket stainless steel?

The two jacketed options are described only as having an iron-sheet jacket. The stainless steel description in the product title concerns the clamps; it does not establish the jacket grade. Confirm the jacket material, finish and construction for the version you need.

Can I read every three-number option as ID, OD and height in mm?

Not without confirmation. The first option explicitly gives ID 32 mm, OD 42 mm and height 90 mm. Matching dimension photos support some other options, but labels without explicit units or an exact photo match remain unconfirmed numeric specifications.

Why do some photo heights differ from the option labels?

The source contains both sets of information. Both are preserved here rather than silently replacing one with the other. State the complete option label and the required height, and identify any conflicting photo reference before ordering.

Are the reducer photos selectable models in this listing?

The 33 dimensional option labels are straight-coupling options. Four source photos show reducers, but none is an exact match to a dimensional option in this listing. Treat them as references for a separate enquiry, not confirmed selectable models.

What should I include in a custom-specification enquiry?

Provide the required dimensions with units, construction details, material requirements, quantity and operating conditions. Custom availability, final specification and commercial terms need confirmation for the individual request.
