Short answer: a useful bag filter housing spare parts kit is built from the exact housing model, serial or drawing, seal material, bag size, closure and installed accessories. Do not order a generic “maintenance kit” without confirming dimensions and materials, because baskets, O-rings, hold-down devices and vent parts can differ even when two housings accept the same nominal filter bag.
This guide is for maintenance buyers, distributors and plant engineers preparing a replacement-parts quotation. It separates operating spares from project modifications and shows which information INCE needs before confirming fit.
Send the housing nameplate, overall photos, closure details, bag size, seal material, quantity and delivery country. INCE will review available replacement or custom-fabricated parts without assuming interchangeability.
Start With Positive Housing Identification
Record the manufacturer, model, serial number, housing size, number of bags, material grade, design pressure, connection standard and closure type. Photograph the nameplate, cover, internal basket, bag hold-down arrangement, vent, drain and any gauge connection. For an INCE single bag filter housing or multi bag filter housing, include the original drawing or purchase reference when available.

Which Spare Parts Belong in the RFQ?
| Part group | Information to submit | Purchase risk if omitted |
|---|---|---|
| Cover seal | Material, cross-section, inside/outside diameter, installed location and service fluid | A seal may fit physically but be unsuitable for the liquid or temperature |
| Restrainer basket | Outside diameter, length, perforation, open-end detail, bottom shape and handle | Incorrect fit may leave the bag unsupported or prevent correct seating |
| Bag hold-down | Photos, spring or plate dimensions, quantity and relationship to the bag collar | Missing restraint can allow movement or bypass |
| Vent and drain parts | Thread/flange standard, size, pressure class, material and valve arrangement | Similar-looking NPT and BSP components are not automatically interchangeable |
| Closure hardware | V-clamp, T-bolt or eye-bolt details, fastener grade and drawing dimensions | Closure hardware is pressure-retaining equipment and must match the design |
| Instrumentation | Gauge range, process connection, wetted material and required certificates | A pressure range or connection mismatch can delay installation |
Eaton’s published bag-housing spare-parts categories include restrainer baskets, bag positioners, gaskets/O-rings, hold-down parts, adapter heads and other accessories. That list is a useful procurement reference, but it does not prove that Eaton or INCE parts interchange with a different vessel. See the official Eaton spare-parts page.

Separate Consumable Spares From Pressure-Boundary Changes
Routine replacement of an agreed O-ring or basket is different from modifying a nozzle, closure or pressure-retaining part. If the request changes pressure, temperature, connection layout or closure design, treat it as an engineering review rather than a spare-part order. Send design and operating conditions, fluid compatibility data and the applicable project code. The filter housing documentation package guide explains how to define drawings, material records and test documents.
How Many Spares Should You Buy?
There is no universal two-year quantity. Base the stocking plan on installed housing count, change-out frequency, seal damage history, cleaning chemicals, planned shutdowns, import lead time and whether parts are common across several units. Classify each item as a wear part, critical single-point spare or non-critical replacement. Ask for individual part numbers and drawings so future orders can be repeated consistently.

RFQ Checklist
- Housing manufacturer, model, serial number and original drawing.
- Single- or multi-bag configuration and bag size.
- Pressure, temperature, process liquid and cleaning chemicals.
- Housing, basket, seal and fastener materials.
- Photos with measurement references; do not rely on visual similarity alone.
- Required quantity per item, installed base and desired stocking period.
- Destination country, requested documents and required delivery date.
Upload the nameplate, drawing and photos with the part quantities. Ask INCE to identify assumptions and exceptions in the quotation so purchasing and maintenance use the same reference.
Frequently Asked Questions
Can I order a bag housing O-ring by bag size alone?
No. Bag size does not define the cover-groove dimensions or seal material. Provide the housing model, seal dimensions, fluid, temperature and photos.
Is a restrainer basket interchangeable between different housing brands?
Not automatically. Confirm diameter, length, perforation, bottom shape, handle, support points and bag seating arrangement.
Should a closure modification be quoted as a spare part?
Usually not. A change to pressure-retaining closure hardware or nozzles requires an engineering review using the housing design basis and applicable project requirements.
