Reliable Sealing Solutions for Industrial and Heavy Equipment
Seal Tech Mackay supports Queensland businesses sourcing oil seals for equipment servicing, component replacement and industrial maintenance.
Sealing options for equipment where lubricant retention and contaminant exclusion are critical.
Send a part number, drawing or sample and we will help confirm what is required.
Oil seals for pumps, gearboxes, axles and machinery used across industry.
Different equipment designs require different sealing arrangements. Understanding the function and construction of the original component helps distinguish between products that may appear similar but serve different purposes.

A hydraulic oil seal serves a specific function within an assembly, depending on its position and design. Before selecting a replacement, establish whether the component retains lubricant, seals a rotating shaft or forms part of another sealing arrangement. This distinction helps prevent the selection of a product that looks similar but does not suit the equipment’s requirements.
A metal oil seal incorporates a metal element in its outer structure. Depending on the design, this may provide rigidity and help retain the component within its housing. When sourcing a replacement, check the original part reference, dimensions and housing arrangement to establish whether the proposed seal matches the existing specification.
A high pressure oil seal must be specified for the pressure range and mechanical conditions of its intended application. A conventional oil seal should not be substituted for a pressure-rated component without confirming its suitability. Check the manufacturer’s operating limits and the equipment specification before approving a replacement.
Planning seal replacements ahead of scheduled maintenance gives workshops time to verify part references and identify missing information. For equipment with several sealing points, check the parts list against the relevant equipment documentation before placing an order.
When preparing an oil seal enquiry, gather the following details.
Provide the equipment manufacturer, model and serial number where available. This information can help establish which parts catalogue or technical documentation applies.
Identify the relevant pump, gearbox, motor, axle or other assembly. Include the part reference or drawing number if you have it.
Specify the quantity required and whether the order relates to an immediate repair or planned maintenance. Include any additional sealing components listed for the same assembly.
Provide the original part number and verified dimensions, including the shaft diameter, housing bore and seal width where applicable. Photographs can help clarify the component’s condition and configuration.
Record the lubricant, temperature, rotational speed and pressure conditions where known. Include any specific requirements stated in the equipment documentation.
Having these details available helps clarify the product enquiry and supports more accurate assessment of the required oil seals.
Oil seal compounds differ in their compatibility with lubricants, chemicals and temperature ranges. Material selection must account for the intended application, alongside the seal profile, dimensions and manufacturer\u2019s specification.
NBR is used in many applications involving compatible oils and lubricants. Its suitability depends on the specific compound, operating temperature and exposure conditions. Confirm compatibility before selecting an NBR seal for a replacement.
FKM compounds are considered for applications requiring resistance to particular oils, chemicals or elevated temperatures. Performance varies by grade, so check the relevant product specification against the intended operating environment.
HNBR can provide a combination of mechanical strength and resistance properties for selected demanding applications. Confirm that the particular compound suits the lubricant, temperature and other operating conditions.
PTFE offers low-friction characteristics and resistance to many chemicals in suitable applications. Its suitability depends on the product design, sealing arrangement and operating conditions. Confirm the manufacturer’s guidance before specifying a PTFE-based component.
Oil seals are available in profiles designed for different mounting arrangements and equipment layouts. The correct profile depends on the original component and how it is retained in the assembly. Where the existing seal is damaged or difficult to identify, use the equipment parts catalogue or an available technical drawing to help establish the required configuration.
Unsure which configuration you need? Send a photo of the existing seal with the housing dimensions and our team can help clarify the options.
