Product Overview

The Leer 736-013 magnetic door gasket is an OEM replacement seal for verified walk-in cooler and freezer door applications. Positioned around the door perimeter, this gasket helps the door close against the frame and maintain a dependable cold-air barrier. A sound door seal matters because gaps around the door can allow warmer, moisture-laden air to enter the refrigerated space, contributing to frost, condensation, and reduced cabinet temperature stability. Door gaskets are wear items that can gradually lose compression, tear, split, harden, or pull away from their mounting channel. Replacing a damaged gasket can help restore consistent door contact and reduce cabinet air leakage when the door, hinges, latch, and gasket mounting area are in good condition. This Leer OEM part is identified by manufacturer part number 736-013, helping commercial refrigeration service teams and facility operators select the correct replacement component. Compare the removed gasket, door details, and equipment data plate information before ordering to help avoid a wrong-part purchase.

Product Function

This magnetic door gasket forms the flexible sealing surface between a walk-in cooler or freezer door and its frame. Its purpose is to support full perimeter contact when the door is closed, helping keep conditioned air where it belongs and limiting outside air entry. The magnetic portion helps the gasket remain engaged with the door frame, while the gasket body provides compression around the opening. When the original seal is worn or damaged, the door may not close evenly or may leave areas where air can pass. The 736-013 gasket is a replacement door-sealing component, not a hinge, latch, or door closer; those related parts should also be inspected when closure problems remain after gasket replacement.

Why Choose a Genuine OEM Replacement?

Leer OEM part number 736-013 provides a reliable identification point when replacing the original door gasket. Matching the manufacturer part number helps reduce confusion among similar-looking magnetic gaskets that may have different profiles, mounting arrangements, or door applications. Using the verified OEM number alongside a direct comparison of the removed component supports a more confident ordering decision for commercial refrigeration service.

How This Part Works

When the door closes, the magnetic gasket draws toward the mating door frame and the flexible gasket material compresses around the perimeter. This contact creates a barrier that helps limit air exchange between the refrigerated space and the surrounding area. Even contact around all sides of the door is important: a gap at one corner, along an edge, or near the latch side can permit warm air and moisture to enter. The gasket works together with the door alignment and closing hardware. Hinges support door position, the latch holds the door closed, and the gasket mounting channel keeps the seal located correctly around the door. If the door is sagging, the latch is not pulling the door into position, or the gasket channel is damaged, a new gasket alone may not correct the sealing concern. Inspecting these related areas helps identify conditions that can affect gasket compression and door closure.

Technician Service Tip

Before replacing the gasket, compare the original component with part number 736-013 and inspect the full door perimeter. Check for tears, flattened areas, loose sections, damage at the gasket mounting channel, and door alignment concerns near the hinges or latch. A clean, intact mounting area and properly aligned door help the replacement gasket make more even contact.

Common Failure Symptoms

• Visible tears, splits, cracks, or missing sections of the door gasket may indicate that the seal should be inspected.
• A door that does not appear to close evenly around the frame can indicate gasket compression loss or a door alignment concern.
• Frost accumulation near the door opening may indicate air leakage at the gasket or another door-sealing issue.
• Moisture or condensation around the door perimeter can indicate that humid outside air is entering through an incomplete seal.
• Flattened or hardened gasket areas may indicate reduced compression against the door frame.
• A gasket that pulls loose from its mounting area should be inspected along with the door channel or retainer.
• Cabinet temperature concerns near a frequently opened door may indicate a door seal, hinge, or latch condition requiring evaluation.
• Light visible around portions of a closed door may indicate a gap that should be inspected for gasket or alignment issues.
• The door requiring unusual pressure to remain closed can indicate a gasket, latch, hinge, or frame-contact concern.
• Uneven contact marks around the gasket may indicate that the door is not meeting the frame consistently.

Commercial Applications

The Leer 736-013 door gasket is identified for verified walk-in cooler and freezer door-sealing applications within commercial refrigeration equipment. Walk-in refrigerated storage is commonly used where food, beverages, ingredients, and temperature-sensitive inventory require controlled cold storage. Restaurant kitchens, foodservice maintenance teams, refrigeration service companies, institutional kitchens, and commercial facilities may need door gasket replacement when an existing seal is worn or damaged. Application confirmation should be based on the verified manufacturer part number, the original gasket, door construction, and equipment data plate details. Although this part is associated with walk-in cooler and freezer doors, door gasket appearance alone is not enough to confirm selection. Comparing the original component and confirming the door details before purchase helps support a correct replacement choice.

Before You Order

• Match Leer manufacturer part number 736-013 to the original component or approved equipment information.
• Confirm that the replacement needed is a magnetic door gasket rather than a hinge, latch, closer, or other door component.
• Compare the removed gasket with the product image, including its overall appearance and magnetic sealing edge.
• Review the gasket mounting arrangement on the door before ordering.
• Inspect the gasket channel or retainer area for damage, looseness, or obstruction.
• Confirm the equipment data plate details, including the equipment identification and serial number.
• Check whether the door closes evenly and whether hinge alignment or latch condition may affect the seal.
• Inspect the original gasket for torn sections, flattened compression areas, or separation from the mounting area.
• Confirm that the door is used on the verified walk-in cooler or freezer application.
• Have a qualified commercial refrigeration service professional evaluate door alignment concerns when needed.

Related Components

• Door hinges: Inspect hinges for looseness, wear, or alignment concerns that can prevent even gasket contact around the door frame.
• Door latch: Inspect the latch because it helps pull and hold the door in its closed position against the magnetic gasket.
• Door closer: Inspect the closer where present, as inconsistent closing action can leave the gasket without full perimeter contact.
• Gasket retainer or mounting track: Inspect the gasket mounting area for damage or looseness that can prevent the replacement seal from staying positioned correctly.

Frequently Asked Questions

What is Leer part number 736-013?

Leer 736-013 is an OEM magnetic door gasket identified for verified walk-in cooler and freezer door-sealing applications.

What does a magnetic door gasket do?

A magnetic door gasket helps a refrigerated door contact the frame around its perimeter, supporting a cold-air barrier and helping limit outside air entry.

How do I confirm that this is the correct door gasket?

Match Leer manufacturer part number 736-013, compare the removed gasket and its mounting arrangement, and confirm equipment data plate details before ordering.

Can a worn door gasket contribute to frost or moisture around a door?

Yes. A torn, flattened, hardened, or poorly seated gasket may allow warmer, moisture-laden air to enter around the door, which can contribute to frost or condensation.

Should hinges and the latch be inspected when replacing a door gasket?

Yes. Door hinges, the latch, the closer where present, and the gasket mounting area can affect door alignment and gasket contact. Inspecting them helps identify related closure concerns.

Is Leer 736-013 a hinge or latch replacement?

No. Leer 736-013 is a magnetic door gasket. Hinges, latches, closers, and gasket mounting hardware are separate door components.
