Rubber Reducer Pipe Coupling with Stainless Steel Clamps

Description

Rubber Reducer Pipe Coupling with Stainless Steel Clamps

This rubber reducer pipe coupling connects different pipe sizes through a stepped rubber sleeve and clamp-style end connections. IKSONIC is a China-based supplier for wholesale reducer-coupling enquiries and custom rubber-part sourcing. The listing contains 26 numeric option labels, with separate photo references showing small-end and large-end dimensions. Confirm the complete specification for your pipes before ordering.

Product Overview

• Connection type: Rubber reducing sleeve with a smaller end and a larger end.
• Clamp material: Stainless steel as stated in the source title; no specific stainless grade or tightening specification is established.
• Selection details: Small-end ID and OD, large-end ID and OD, and overall height. A pair of nominal pipe sizes alone does not establish the required sleeve dimensions.
• Material enquiry: The promotional offering mentions rubber, silicone, EPDM, NBR, natural rubber and fluororubber. These are possible material categories to discuss, not a fixed formulation assigned to every option.
• Custom requirements: Other specifications are listed for custom enquiry, with dimensions and commercial terms to be confirmed individually.

Specifications / Models

26 Listed Reducer Options

All 26 numeric option labels appear below. The separate custom-processing placeholder has no dimensions and is excluded from the count. The first label, 50-65 * 60-75 * 90, states neither units nor the meaning of its numeric groups, so it is preserved without assigning ID, OD or height. Most other labels explicitly state mm for height only. End values should be treated as confirmed ID dimensions only where supported by a matching photo reference or separately confirmed.

Complete reducer option list with dimensional uncertainties preserved

No.	Option values as listed	Dimensional reference / confirmation needed
1	Reducer 50-65 * 60-75 * 90	Units and the meaning/order of the numeric groups are not stated. Retained unchanged; confirm every dimension before ordering.
2	Reducer 12.7-50.8; height 100 mm	Photo 27 shows small-end ID 12.5 mm, not 12.7; large-end ID is 50.8 mm and height is 100 mm. Both values are preserved; confirm the required small end.
3	Reducer 25-75; height 125 mm	No exact photo match. Photo 29 instead shows end IDs 25.5 mm and 76.2 mm, with height 125 mm; do not substitute those values.

15 Distinct Source-Photo Dimension References

Sixteen source photos contain dimensional annotations. Photos 16 and 24 are identical and are combined below, giving 15 distinct references. All five dimensions in this table are explicitly labelled in mm in the respective photo. Thirteen references match a listed pair of end-size values and height; two are photo-only references. Photo evidence is kept separate from option labels and must not be used to silently change them.

Reducer small-end and large-end dimensions, all in millimetres

Photo reference	Small-end ID (mm)	Small-end OD (mm)	Large-end ID (mm)	Large-end OD (mm)	Height (mm)	Relationship to listed options
16 / 24	145	155	160	170	110	Photo-only reference with no matching option label. Source photos 16 and 24 show identical dimensions and are combined in this row.
17	80	90	95	105	100	Matches the listed end-size and height values of Reducer 80-95; height 100 mm.
18	90	105	105	115	90	Matches the listed end-size and height values of Reducer 90-105; height 90 mm.
19	78	88	88	98	54	Matches the listed end-size and height values of Reducer 78-88; height 54 mm.
20	63	73	160	170	100	Matches the listed end-size and height values of Reducer 63-160; height 100 mm.
21	63	76	90	103	50	Matches the listed end-size and height values of Reducer 63-90; height 50 mm.
22	160	170	185	195	150	Matches the listed end-size and height values of Reducer 160-185; height 150 mm.
23	40	50	50	60	90	Matches the listed end-size and height values of Reducer 40-50; height 90 mm.
25	114	124	140	150	130	Matches the listed end-size and height values of Reducer 114-140; height 130 mm.
26	75	85	110	120	100	Matches the listed end-size and height values of Reducer 75-110; height 100 mm.
27	12.5	22.5	50.8	60.8	100	Photo-only reference: small-end ID is 12.5 mm, while the 12.7-50.8 / height 100 mm option lists 12.7. Do not replace either value.
28	25	35	35	45	132	Matches the listed end-size and height values of Reducer 25-35; height 132 mm.
29	25.5	35.5	76.2	86.2	125	Matches the listed end-size and height values of Reducer 25.5-76.2; height 125 mm.
30	40	50	160	170	100	Matches the listed end-size and height values of Reducer 40-160; height 100 mm.
31	63	73	75	85	63	Matches the listed end-size and height values of Reducer 63-75; height 63 mm.

Small-end discrepancy: The option 12.7-50.8 / height 100 mm retains the value 12.7. Photo 27 explicitly shows small-end ID 12.5 mm and OD 22.5 mm, large-end ID 50.8 mm and OD 60.8 mm, and height 100 mm. Neither source value has been corrected or rounded to match the other. Confirm whether 12.7 or 12.5 is required before ordering.

Keep similar options separate: The 40-50 options list heights of 100 mm and 90 mm, and the 63-90 options list heights of 100 mm and 50 mm. The matching photos support only the indicated height. Likewise, 25-75 / height 125 mm is not the same listed option as 25.5-76.2 / height 125 mm.

How to Specify a Reducer Coupling

1. Measure the actual outside diameter of each pipe end. Identify the smaller end and the larger end rather than relying on a nominal pipe designation.
2. Provide the required sleeve ID and OD at both ends, plus overall height and units. Quote the complete option label and any relevant photo reference.
3. Describe the conveyed medium, working pressure, temperature and installation environment so the rubber compound and assembly requirements can be checked.
4. Confirm the clamp specification, pipe engagement and installation instructions for the selected version, along with the required quantity.

This listing does not establish a verified pressure rating, service-temperature range, hardness value or certification for the complete reducer assembly. Material names and general promotional charts are not substitutes for application-specific confirmation.

Frequently Asked Questions

What do the two end-size values mean?

Matching photos identify the small-end and large-end inner diameters and give their outer diameters separately. An option label without a matching photo may not state whether its end values are ID or OD, or what units they use. Confirm those details rather than applying one interpretation to every label.

Should the 12.7 option be changed to 12.5?

No automatic change should be made. The option and photo show different small-end values, and both are retained for reference. State the required small-end dimension explicitly when asking IKSONIC to confirm the specification.

Does a matching height confirm the entire reducer size?

No. Both end diameters and their measurement basis must also match. For example, the 25-75 and 25.5-76.2 options both list height 125 mm, but their end-size values differ.

Can I choose the rubber formulation from the photo?

No. The product appearance does not establish the compound. The source promotes several material categories, but the actual material for your selected size and operating conditions needs confirmation.

What is needed for a custom reducer enquiry?

Provide all five sleeve dimensions with units, the required material, quantity and operating conditions. Add the exact option label if you are modifying a listed size. Any unlisted specification must be checked before an order is placed.
