What is a flexible waterproof sleeve?
A flexible waterproof sleeve uses a specified housing and sealing assembly around a pipe penetration. Its bolted gland and seal arrangement must be selected for the carrier pipe, wall detail and required movement conditions.
Key dimensions and installation fit
The wall sleeve forms a controlled pipe penetration through a wall or slab. Check the actual carrier-pipe diameter, sleeve diameter, wall thickness and installation depth. A puddle flange addresses the wall interface; a flexible gland or seal addresses the gap between the sleeve and carrier pipe. Review pipe supports and hangers when coordinating the carrier-pipe support arrangement with the penetration detail.
How to specify the flexible waterproof sleeve
Coordinate sleeve material, coating and sealing components with the wall construction and pipe service. Nominal DN alone does not define the annular gap. If movement accommodation is required, specify its direction and permitted displacement rather than assuming that every flexible waterproof sleeve has the same movement capability.
Technical data for the flexible waterproof sleeve
| Nominal size | DN100 |
|---|---|
| Carrier-pipe diameter D1 | 108 mm |
| Sleeve diameter D2 | 146 mm |

| Gland length l | 65 mm |
| Series size range | DN50–DN1000 |
Sizes and dimensional requirements
The dimensional schedule identifies the illustrated configuration. Compare each value with the mating pipe, equipment or support drawing. A nominal designation does not replace the actual connection diameter, installation envelope or mounting detail. The choices above let you include a different configuration with your quotation request.
Dimensions and tolerance schedule
| Machined length >30–120 mm | ±0.3 mm |
|---|---|
| Machined length >120–400 mm | ±0.5 mm |
Inspection, standards and documentation
Inspect the carrier-pipe surface, sleeve position, flange or gland dimensions and accessible fasteners. Coordinate the assembly with the concrete detail, wall thickness and waterproofing system. Include the required sealing test, installation orientation and finish in the enquiry.
State the required product standard and edition, material records and inspection acceptance criteria before ordering. Where pressure, temperature, movement or load are relevant, provide the operating and test conditions together. Document requirements should identify the actual component and drawing revision; a general certificate does not replace a dimensional or material record for the ordered item. Use the pipe support and casing manufacturing guidance to confirm fabrication and inspection requirements.
Where the flexible waterproof sleeve is used
- Wall pipe penetrations. Coordinate the sleeve position with wall thickness, carrier-pipe diameter and waterproofing.
- Floor penetrations. Review the embedded assembly and accessible sealing components.
- Waterproofing interfaces. Specify the sealing duty and any required pipe movement accommodation.
How to order a flexible waterproof sleeve
Select the required options and send the quantity, destination, material and controlled drawing to JINYI. Include changed dimensions, mating details, finish, marking and packing requirements. The quotation defines the final configuration, inspection scope and delivery terms so the component can be checked against the intended installation.
Quantity prices and order preparation
| 1,000–1,999 pcs | US$10.00 per piece |
|---|---|
| 2,000–4,999 pcs | US$9.50 per piece |
| 5,000 pcs and above | US$9.00 per piece |
Freight and taxes are quoted separately. A different material, size or drawing can change the price and delivery requirements. Confirm the agreed specification before manufacture, and keep the drawing revision, selected options and ordered quantity together in the enquiry.

Flexible Waterproof Sleeve selection and quotation checklist
The gland and seal arrangement differentiates this sleeve from a rigid casing. Specify the carrier pipe outside diameter, wall detail and permitted movement at the penetration. Use the photographed product form to identify the arrangement, then use the controlled drawing to define what will be supplied. Similar-looking components can have different end details, load paths or maintenance requirements.
Flexible Waterproof Sleeve dimensions and tolerances
The first comparison for this flexible waterproof sleeve is gland dimensions and sealing clearance. Mark the dimensions that control mating, alignment and installation space on the enquiry drawing. Give units for every value and identify the datum from which it is measured. If a dimension is critical, specify its individual tolerance and measurement method rather than relying on a general tolerance note.
The current schedule identifies nominal size: DN100; carrier-pipe diameter d1: 108 mm; sleeve diameter d2: 146 mm. Read these entries together with the configuration and tolerance tables above. Reference or example values describe the displayed arrangement; the approved JINYI quotation and drawing define the ordered component. A different interface, material or service condition needs a fresh comparison.
Prepare the material and interface information
For a flexible waterproof sleeve enquiry, identify the required material designation and supplied condition. Describe the mating components, attachment method and environment. Include the operating temperature and any relevant pressure, movement or structural load. These inputs should describe the actual installation, including changes between normal operation, start-up and maintenance where applicable.
Specify coatings, surface finish and marking separately from the base material. If traceability is needed, identify the record required and how it must correspond to the delivered component. Agree whether inspection covers dimensions, material documentation, welds or functional testing; these are different checks with different acceptance criteria.
Custom flexible waterproof sleeve quotation
Attach the latest drawing revision, required quantity and delivery destination when contacting JINYI. Highlight departures from the illustrated arrangement, including changed dimensions, connections, finish and packing. For repeat orders, reference the approved configuration and list changes explicitly so an earlier drawing is not assumed to remain current.
The three price tiers above organise the displayed quantity bands. Compare quotes using the same drawing, material, inspection scope and unit of supply. A piece, a segment and a complete assembly are different units where applicable. Confirm freight, taxes, documentation and delivery terms with the final quotation instead of inferring them from the displayed unit price.

Questions to resolve before ordering
Which dimensions need checking first?
Start with gland dimensions and sealing clearance and the mating or mounting detail. Check nominal designations against measured dimensions, then review the installation envelope. Photographs help identify the form; the drawing provides the dimensional basis for acceptance.
What should the quotation include?
A flexible waterproof sleeve quotation should identify the configuration, drawing revision, material, quantity, price basis and agreed inspection records. Keep these details together with the approved order so receiving inspection can compare the delivered product with the specified component.
