The exact wear-band reference
These hydraulic guide rings are the WB0091-0375-080-N1-A reference. The researched construction is glass-filled nylon with an angle cut. Dimensions are 0.750-inch inside diameter, 0.910-inch outside diameter, 0.375-inch height and 0.080-inch wall thickness. Each dimension belongs to this one fixed product reference.
Keep the full SKU, including its suffix, when comparing a replacement. The request is not for an arbitrary length of material or an assortment of ring diameters. Another material, cut style or dimension would need a separate verified product match.
Four dimensions, four separate checks
Inside diameter and outside diameter describe the two diameters of the ring. Height describes the axial dimension, while wall thickness describes the radial thickness. These values are not interchangeable. In particular, the 0.375-inch height should not be described as the wall thickness.
The recorded diameters differ by 0.160 inch. Half that difference is 0.080 inch, consistent with the listed radial wall thickness. This arithmetic is a useful transcription check, not a new tolerance specification or an instruction to machine a housing to those dimensions.
Match the installation drawing
Compare the complete wear-band reference with the equipment drawing and original parts list. Check the required diameters, axial space and material together. If a parts list uses the terms wear ring, guide ring or wear band, retain the exact part number alongside the description so the name alone does not become the basis for a substitution.
The installation dimensions and required clearances come from the equipment design. This page does not derive a groove diameter, allowable running clearance or housing tolerance from the ring dimensions. Those are separate engineering requirements that must be resolved before choosing a replacement.
Glass-filled nylon and the cut style
The researched material is glass-filled nylon. That is a more specific description than plastic and should not be shortened to a generic material claim when comparing alternatives. A PTFE, fabric-reinforced or metal component is not represented as the same product simply because its dimensions look close.
The recorded cut style is angle cut. Keep that feature in the product comparison rather than inferring a continuous ring or another joint from the illustration. The exact reference is the source of the material and cut description; the image is only a visual aid.
Guide rings and other cylinder components
The request identifies a wear-band component. It does not include a pressure seal, rod wiper, piston, bearing housing or complete cylinder repair kit. Those parts can appear together in equipment documentation, but their presence in an assembly does not make them part of this product.
If a maintenance task involves several different components, keep their references and quantities distinct. Three bands in the proposed pack do not establish that a particular cylinder needs three bands. The number required in an installation must come from the actual equipment arrangement.
What the specification does not establish
The recorded listing identifies material, cut and dimensions. It does not establish an application-specific pressure, temperature, speed or load rating on this page. Those values should not be inferred from the material name or borrowed from another ring in a catalogue.
Use the component drawing and appropriate technical documentation to resolve operating suitability. The availability request can remain attached to the exact researched part while that assessment is completed; it should not be interpreted as an engineering approval or authorization to install the component.
How to use the product illustration
The illustration helps identify the general ring form and angled joint. It is not to scale, and the apparent gap, surface texture or thickness is not a manufacturing tolerance. Use the specification rather than a pixel measurement to compare the part.
For a replacement comparison, record the dimensions from the original drawing with their labels. That prevents the height and wall thickness from being transposed and keeps the inside diameter separate from a housing dimension. The complete SKU provides a further check against a similar-looking size.
The proposed three-band pack
One proposed Plethara pack represents three WB0091-0375-080-N1-A bands. Requested quantity means packs: two packs represent six bands of this exact reference. The grouping does not include a mix of sizes or another material.
This is a proposed basis for the availability inquiry, not a promise of supplier packaging, inventory or final unit price. The review screen retains the pack basis and requested quantity with the exact SKU so the intended number of components remains clear.
Requesting guide rings
Enter your name and email with the requested pack quantity, then check the product and grouping on the review screen. Confirming records interest in this exact wear-band reference. It does not create an order, reserve stock or authorize a substitution.
Availability, final price and delivery timing will be confirmed before any purchase. No payment is collected and no charge or fulfillment is authorized. Other parts or a different material require their own verified references rather than being assumed to accompany this request.
Questions about WB0091-0375-080-N1-A
- Which material are these guide rings?
- The researched WB0091-0375-080-N1-A reference is glass-filled nylon with an angle cut.
- Is 0.375 inch the wall thickness?
- No. It is the height. The recorded wall thickness is 0.080 inch.
- Does one requested pack contain one band?
- No. One proposed pack represents three bands of the exact same reference.
- Is this a complete hydraulic seal kit?
- No. The request covers wear bands only, without pressure seals, wipers or other cylinder components.
- Can I use the listed dimensions as housing tolerances?
- No. Component dimensions and installation tolerances are different specifications. Check the equipment drawing.
