How to Prepare a Multi-Item Seal RFQ: Part Identification and Packing Data

A mixed seal inquiry can include oil seals, O-rings, drawing-based parts and shaft-mounted V-rings in one list. The challenge is to keep each requirement attached to the correct part while collecting comparable packing information. A clear request for quotation lets the supplier identify uncertainties before a description, drawing or weight is assigned to the wrong line.

Build the inquiry around stable item references. Keep technical identification and packing data in separate fields, but connect both to the same item number. This makes later revisions easier to trace.

Give every item an unambiguous identity

Assign a unique line reference that remains unchanged when the list is sorted or revised. Identify the seal family, reference designation, requested material and relevant dimensions, with units. Put quantities in their own field rather than embedding them in a product description.

Use the dimensional reference appropriate to the part. For an O-ring, distinguish inside diameter from cross section. For a radial oil seal, identify shaft, housing and width references. For a shaft-mounted V-ring, distinguish its applicable shaft diameter from its free-state bore. Do not force every seal into one unlabeled diameter field.

Match drawings and samples to the correct line

List the drawing identifier and revision beside the item it describes. Name attachments consistently and include a simple attachment index if several parts have reference images or drawings. Identify whether a sample is the requested part, an approximate reference or a used component whose condition needs assessment.

Ask the supplier to repeat the item reference in its technical response. A proposed replacement should be identified separately from the original reference. If one proposal covers several items, request an explicit mapping rather than relying on attachment order or a general statement that the list can be supplied.

Separate specified requirements from proposals

List known material and construction requirements without filling gaps with guesses. A polymer family alone may not establish the complete compound or finished seal construction. Mark unknown requirements and ask for a documented proposal or clarification against each affected item.

Where dimensions or designations are ambiguous, request the proposed drawing, section or catalogue reference. Keep unresolved differences visible in the response. An apparently complete item list is less useful than one that clearly distinguishes confirmed information from details still awaiting technical agreement.

Define what each weight includes

Request net product mass on a stated basis, such as per piece or for the quantity on that line. For this inquiry, define net mass as the product itself, excluding packaging. State the units and ask whether the value is measured or estimated. This avoids comparing a unit mass with a line total.

Request gross mass for each planned packed unit, including its packaging. Identify whether that packed unit is an inner pack, carton, crate or palletized shipment. Ask the supplier to describe what is included, especially if several line items share a carton or pallet. The sum of product masses alone does not describe a packed shipment.

Connect the packing plan to the item list

Useful packing information includes:

• Item reference and quantity assigned to each pack.
• Number of packs and any mixed-item carton contents.
• External packed dimensions, units and orientation where relevant.
• Net and gross mass on the stated measurement basis.
• Packaging type, labels and identification needed for receiving.
• Whether the information is provisional or confirmed after packing.

Ask for parts to remain identifiable during receiving, with the item reference connected to the appropriate label or packing-list entry. Request a packaging proposal that protects the seal’s shape and sealing features. Agree on requirements that matter for inspection or handling rather than assuming all seal families use the same packing method.

Keep revisions easy to reconcile

When changing a drawing, quantity or material requirement, issue a clear revision to the affected lines. Ask the supplier to identify which technical and packing entries have changed. If the packing plan depends on the final order mix, distinguish current estimates from confirmed shipment data.

Short FAQ

Can one total weight cover the whole inquiry?

A total can support planning, but request enough item and pack information to understand what it contains and which quantities it covers.

Should estimated packing data be treated as final?

Label estimates clearly and request confirmation when the packed quantities and packaging arrangement are established.

Can I attach drawings without an item index?

An index helps connect every attachment and revision to the correct line, especially when several seals look similar.
