Flexible PVC Ventilation Duct Couplings with Clamps

Description

Flexible PVC Ventilation Duct Couplings with Clamps

These flexible PVC duct couplings are listed for pipe and fan connections in fresh-air ventilation systems. The range includes straight and reducing connections, with clamps included in all 18 options. IKSONIC is a China-based supplier for wholesale ventilation-component sourcing. Compare the listed end codes with actual duct dimensions before selecting a coupling.

Material and Construction

• Coupling body: Flexible PVC, explicitly identified in the product parameter panel. References to PE pipe describe the intended pipe context, not the coupling material.
• Included hardware: Every listed option states that clamps are included. The supplier describes the clamps as 304 stainless steel in the product detail image; confirm the hardware specification required for your order.
• Connection choices: Straight and reducer options, with individual end-size labels and stated heights where supplied.
• Application context: Fresh-air ventilation duct and fan connections. Final fit depends on actual pipe outside diameters, coupling bore dimensions and the installation requirements.
• Dimension basis: Nominal option codes and measured parameter values are presented separately below.

Specifications / Models

All 18 Listed Options

Clamps are included in every row. Heights are reproduced only where the option label supplies them. End-size labels are selection codes, not guaranteed measured coupling IDs or ODs. The final 185-195 to 200 label does not state end-size units or explain the 185-195 notation, so that information remains unconfirmed.

The source parameter panel separately lists seven summary model codes: 100-75, 100-90, 100-110, 150-110, 150-160, 200-160 and 200-200. These are already represented in the option list; they are not seven additional models and do not define the unlisted dimensions of the other options.

Four Dimensioned Parameter References

The parameter panel gives the following measurements for four codes only. As oriented in its drawing, A is the upper-end inner diameter, B is the upper-end outer diameter, C is the lower-end inner diameter, D is the lower-end outer diameter, and H is the height shown. All table values are in mm. “Upper” and “lower” refer to that drawing orientation, not an installation direction or the order of the nominal end codes.

Source drawing dimensions in mm, limited to the four identified model codes

Model code	A: upper ID	B: upper OD	C: lower ID	D: lower OD	H	Comparison with option label
100-90	90	103	100	115	102	Option height is 100 mm; parameter H is 102 mm. Confirm the required height.
100-110	101	114	113	127	100	Height agrees with the option label. Use the actual A/B/C/D values rather than the nominal code.
150-160	152	164	162	174	104	Height agrees with the option label. Use the actual A/B/C/D values rather than the nominal code.
200-200	202	215	202	215	103	Option height is 106 mm; parameter H is 103 mm. Confirm the required height.

Two height differences require confirmation: The 100-90 option states height 100 mm, while its parameter row gives H = 102 mm. The 200-200 option states height 106 mm, while its parameter row gives H = 103 mm. Both records are retained unchanged; neither value is substituted for the other.

The source describes these as manually measured dimensions without specifying a numerical tolerance. Confirm the actual supplied part and any required tolerance before ordering. Do not extend these four parameter rows to other options. For example, the 100-110 code has stated inner diameters of 101 mm and 113 mm, while the 200-200 code has stated inner diameters of 202 mm at both ends; nominal labels do not equal measured bore dimensions.

Selection Checklist

1. Identify the duct, pipe or fan connection and measure the actual outside diameter of each mating end.
2. Select the intended straight or reducer option and check the complete coupling dimensions. Use the A/B/C/D reference only for its identified code.
3. Confirm the required height, especially for the two options whose labels differ from the parameter table.
4. Provide quantity, installation conditions and any required material, hardware or performance specifications for confirmation.

The source does not establish a verified pressure rating, service-temperature range, quantified vibration reduction, leakage classification or certification for the assembly. Promotional sealing and corrosion-resistance statements should not be treated as unconditional performance guarantees for every installation.

Frequently Asked Questions

Is the coupling PVC or PE?

The source parameter panel specifies flexible PVC for the coupling body. PE appears in the pipe-connection context of the title; it does not identify the coupling itself as polyethylene.

Are clamps included?

Yes. All 18 source option labels explicitly include clamps. The supplier detail describes 304 stainless steel clamps for this product. Confirm the required hardware specification and installation instructions for your selected option.

Does a 100-110 code mean the bores measure exactly 100 mm and 110 mm?

No. The parameter row for that code gives A = 101 mm and C = 113 mm for the two inner diameters. Compare the actual measured dimensions and mating pipe outside diameters rather than treating nominal labels as exact bore sizes.

Which height should I use when the label and table disagree?

Quote both values and state the height required by your installation. For 100-90, the option says 100 mm and the table says 102 mm. For 200-200, the option says 106 mm and the table says 103 mm. The correct supplied version needs confirmation before ordering.

Can the four parameter rows be used for every size?

No. They apply only to the four named model codes. The remaining options need their own dimensions confirmed, including any unstated height and the interpretation of the 185-195 to 200 notation.
