Oil Seal Quote: What to Send and How to Request Pricing

Quick Answer: An oil seal quote requires the seal type, dimensions, material, and operating conditions. Send the shaft diameter, housing bore, width, temperature, fluid, pressure, shaft speed, and required quantity to CORASEALS for a quotation.

Oil seal pricing changes with size, material, lip design, quantity, and special requirements. A complete oil seal quote request reduces back and forth. A complete quote request also helps the supplier verify that the seal fits the shaft, housing bore, and installation space before pricing.

CORASEALS supplies oil seals, rotary shaft seals, radial shaft seals, lip seals, and related sealing products for industrial buyers, repair shops, distributors, and equipment builders. The guide below explains what we need for an oil seal quote.

What to Include in an Oil Seal Quote Request

Send the following details when requesting an oil seal quote from CORASEALS. A drawing or sample photo is always preferred when the type code is unclear.

Seal type or profile: single lip, double lip, metal case, rubber covered, cassette seal, V-ring, or another profile. Include the type code if you have one, for example TC or SC. Type codes can differ between catalogs, so a cross section drawing matters.
Dimensions: inside diameter × outside diameter × width. State the units in millimeters or inches.
Shaft diameter and housing bore: If the seal installation is new, provide both measurements plus the width.
Material: NBR, FKM, HNBR, EPDM, silicone, PTFE, or another compound. Material must match the fluid and temperature.
Operating conditions: medium, temperature range, pressure, shaft speed in rpm or m/s, runout, and shaft surface finish.
Quantity: sample quantity, prototype quantity, or annual volume. Quantity affects unit price and possible tooling.
Drawing, photo, or reference number: A clear drawing or sample photo helps identify the lip type and case design.

Oil Seal Dimensions and Measurement

Oil seal dimensions follow the order ID × OD × width. The inside diameter matches the shaft, the outside diameter matches the housing bore, and the width matches the installation space. A small error in any of these measurements causes leakage or damage during installation.

Confirm the unit on your drawing before sending an oil seal quote request. Do not mix millimeters and inches. If the seal was removed from a machine, measure the metal case OD, the flexible lip ID, and the overall width. Take more than one measurement if the old seal is worn or deformed.

When the shaft is scored or worn, mention the shaft condition in the quote request. A repair sleeve or a different lip design may be required. Shaft runout, surface finish, and installation depth also affect seal life.

Operating Conditions That Affect an Oil Seal Quote

The same oil seal dimensions may require different materials and lip designs depending on the application. A gearbox oil seal running at high shaft speed needs a different lip arrangement than a low speed wheel hub seal. CORASEALS needs the fluid, temperature, pressure, and shaft speed to quote the correct oil seal.

EPDM is not suitable for most mineral oil environments. Nitrile NBR works in many general oil sealing applications. FKM and HNBR are used when temperature or chemical resistance is higher. The fluid matters more than temperature in some cases because a material can survive heat but swell in the wrong fluid.

Shaft speed and pressure also matter. High speed lip seals often need special lip geometry or lower interference. High pressure applications may require a retained case, a different spring design, or a backup ring. Tell us the actual speed range and any pressure spikes.

Oil Seal Type and Material Considerations

Common oil seal profiles include single lip, double lip, spring loaded, metal case, rubber covered, and cassette designs. Type codes such as TC, SC, and TB are widely used, but their exact meaning can vary between catalogs. CORASEALS does not quote an oil seal from a type code alone. We confirm the cross section, case style, lip arrangement, and dimensions.

Material selection depends on the fluid, temperature range, shaft speed, and contamination. NBR suits many mineral oils and greases. FKM handles higher temperatures and many chemicals. HNBR offers better wear and heat resistance than standard NBR. Silicone can be used in some low torque or high temperature applications, but silicone has poor abrasion resistance in many oils. PTFE and filled PTFE seals are used when low friction or chemical resistance is required.

If the application is not clear, send the equipment type, such as a gearbox, pump, axle, motor, or wheel hub. Also send the oil type or chemical name. Equipment type and oil type help CORASEALS compare the seal profile and material against the real operating conditions.

How to Request an Oil Seal Quote from CORASEALS

Write a short message that includes the seal type, material, ID × OD × width, operating temperature, pressure, medium, shaft speed, drawing, sample photo, and required quantity. If you have multiple sizes, send a list with dimensions and quantities. Use one request for matching O-rings, gaskets, or seal kits if those items are also needed.

Send the oil seal quote request through the website or by email. Use the subject line "Oil seal quote request" and attach any drawing or photo. If the equipment data is limited, send a sample photo and the shaft measurement. A clear photo of the old seal marking also helps.

For custom oil seals, include the groove or housing dimensions if the drawing is available. For standard oil seals, include the shaft diameter, housing bore, and width. The more data you provide, the more accurate the oil seal quote will be.

Frequently Asked Questions About Oil Seal Quotes

What information do I need to request an oil seal quote?
Provide the seal type, ID × OD × width, shaft diameter, housing bore, material, temperature, fluid, pressure, shaft speed, drawing, sample photo, and quantity.

What dimension order should I use for oil seals?
Oil seal dimensions are listed as inside diameter × outside diameter × width. Confirm the units in millimeters or inches before sending the request.

Can I get an oil seal quote without a drawing?
Yes. If a drawing is not available, send a sample photo and measure the shaft, housing bore, and width. A photo of the old seal marking also helps.

How do I choose between NBR and FKM for an oil seal?
NBR is common for mineral oils and greases at moderate temperatures. FKM is selected for higher temperatures or aggressive chemicals. Send the fluid type and temperature range so CORASEALS can recommend the right material.

Why does shaft speed affect an oil seal quote?
High shaft speed changes lip heat generation and wear. High shaft speed can require a different lip geometry, lower interference, or another material. Provide the shaft speed in rpm or m/s with the quote request.

Send us the seal type, material, ID × OD × width, operating temperature, pressure, medium, shaft speed, drawing, sample photo, and required quantity. CORASEALS will prepare an oil seal quote based on the details you provide.
