Doorseal – Gasket Inner for High Cube Reefer containers, HZ-069994

Refrigerated containers, known as reefers, represent a key element in the global logistics of sensitive commodities – from food through pharmaceutical products to chemicals requiring a stable temperature. Even the smallest door leakage can lead to warm air penetration, increased humidity and subsequent spoilage of the entire shipment. Therefore, a quality door gasket is an absolute necessity. In this article, we introduce you to the high-performance inner door gasket HZ-069994, designed specifically for refrigerated High Cube containers (HC).

Technical specifications

The precise parameters will help you verify compatibility with your container:

• Tare weight: 1.5 kg
• Material: EPDM (ethylene propylene diene rubber)
• Length: 2,500 mm
• Gasket type: inner door gasket with single blade
• Part designation: 06-007-02
• Purpose: inner door wing of a refrigerated High Cube (HC) container

The length of 2,500 mm corresponds to the perimeter of the door opening of a standard High Cube container, so the profile covers the entire area without unnecessary joining. The weight of 1.5 kg testifies to a robust construction that, however, does not restrict door handling in any way.

What is the HZ-069994 gasket and what is it used for

The gasket designated HZ-069994 (original part 06-007-02) is a perimeter rubber profile designed for the inner door wing of a refrigerated High Cube container. Its single sealing edge (one blade) creates a precise inner barrier that eliminates air leaks, maintains the required cargo temperature and prevents moisture penetration during transport and storage. It is a spare part whose dimensions and properties correspond to the original specification, so it can be used without complications for repairs or replacement of worn gaskets.

Why quality gasket is key

In refrigerated containers, a hermetic seal is absolutely essential. Even a small gap in the gasket can cause:

• Leak of cooled air – the cooling unit then has to work more intensively, energy consumption rises and the service life of the equipment decreases.
• Temperature fluctuation – cargo intended for a precisely defined temperature regime (e.g. −18 °C for frozen goods) can heat up, leading to rejection of the shipment upon receipt.
• Moisture ingress – condensation or rainwater inside the container causes mould, slippery floors and damage to packaging.
• Odor contamination – through leaks unwanted odors can penetrate into the interior, affecting the quality of the transported food.

The HZ-069994 gasket solves these problems. Its single-blade design is designed to perfectly adapt to irregularities when the door is closed and create a reliable barrier.

Main advantages of EPDM material

EPDM is a synthetic rubber that is used in logistics and transport precisely for its exceptional durability. Compared to common natural rubber, it offers:

• Excellent resistance to weather conditions – EPDM does not crack even under long-term exposure to UV radiation, ozone and extreme temperatures from −40 °C to +120 °C.
• Constant elasticity – the gasket retains its shape and elasticity even after many hundreds of door opening and closing cycles.
• Chemical resistance – it is resistant to weak acids, alkalis, water and steam, so it is not damaged by common cleaning agents or condensate.
• Low water absorption – EPDM practically does not absorb water, which is key to maintaining a dry environment inside the container.

Thanks to these properties, the HZ-069994 gasket provides long-term reliability without the need for frequent replacement.

Who the gasket is designed for

This part will be appreciated mainly by:

• Operators and owners of refrigerated High Cube containers – whether the containers are used for transport, rental or storage.
• Transport and logistics companies – for whom cooling reliability is a competitive advantage and prevention of cargo damage is a financial necessity.
• Service centres and container repair shops – the gasket is an exact replacement of the original part, which simplifies stock inventories and repairs.
• Companies operating refrigerated warehouses from containers – even in static applications, the doors must be perfectly sealed to prevent heat losses.

Use and installation

The HZ-069994 gasket is designed for the inner door wing of a refrigerated High Cube container. Installation is usually simple – the profile is fitted into the groove in the door frame, where it is held by form-fit fixation. Given the length of 2,500 mm, it covers the entire perimeter and does not need to be joined. Before installation, we recommend thoroughly cleaning the groove of old adhesive residues or dirt. With some door types, it may be appropriate to use installation lubricant (e.g. soapy water), which will make it easier to slide the profile into the groove. Then it is sufficient to seat the gasket evenly and check that it fits around the entire perimeter without twisting.

Maintenance and service life

For the gasket to last as long as possible, it pays to follow a few simple principles:

• Regularly check that it is not mechanically damaged (cracks, chips).
• Keep the sealing surface clean – dirt and grease can reduce adhesion.
• Occasionally treat the gasket with silicone oil, which restores elasticity and prevents drying out.
• If signs of permanent deformation or loss of elasticity appear, proceed with replacement.

Under normal operation and proper maintenance, the EPDM gasket will last for many years even in the demanding conditions of maritime transport.
