Description

The Medium Duty Pull Tight Seal is the most widely used pull-tight seal in the Navacqs range. This reliable plastic seal is strong enough to withstand tension (12 kg breaking strength) but can still be broken by hand with moderate force. Thanks to its durable design, high-quality materials, and food-safe construction, the MPT is suitable for a wide variety of applications in logistics, transportation, and industry.

Multifunctional 25 cm Seal

The Medium Duty Pull Tight Seal measures 25 cm (10 inches) in length and is designed for general use. Its compact size and flexibility make it ideal for sealing trucks, drums, couplings, and other logistical applications. With a breaking strength between the lighter Light Duty Pull Tight Seal (7 kg) and the heavier Heavy Duty Pull Tight Seal (22 kg), the MPT offers the perfect balance between security and convenience.

Strong Tail with 12 kg Breaking Strength

The MPT features a sealing tail with a diameter of 2.8 mm, making it easy to insert through narrow openings while providing sufficient tensile strength for everyday use. The HDPE (High-Density Polyethylene) construction ensures rigidity, durability, and resistance to temperatures from -40°C to +80°C.

Delrin® Insert for Hygiene and Food Safety

The MPT’s locking mechanism contains a Delrin® insert, a patented acetal (POM)-based plastic. This material replaces metal components and prevents the release of small particles through friction, making the seal suitable for food processing and medical applications. Delrin® is also exceptionally strong and heat-resistant up to +120°C, extending the seal’s lifespan.

Reliable in Any Environment

The combination of HDPE and Delrin® makes the Medium Duty Pull Tight Seal resistant to chemicals, moisture, and UV radiation. This ensures long-lasting effectiveness even in outdoor environments. Its flexible design allows the seal to be securely tightened, providing both physical integrity and visual tamper evidence.

Unique Marking and Customization

Each MPT seal comes with the standard imprint “MPT 10 SEALED” and a unique serial number produced only once. This guarantees traceability and prevents fraud. The seal can be customized with your company logo, name, or barcode and is available in various colors upon request.

Frequently asked questions

An MPT is a plastic pull-tight seal (a seal you insert through an opening and pull tight) with a breaking strength of 12 kg that can be broken by hand with some force. The MPT is used to seal trucks, drums and couplings where control is needed without the seal having to be removed with tools straight away.

For example, on a truck that's inspected on arrival. The seal stays in place during transport, but can be removed by hand by the recipient without cutters.

The MPT has a 2.8 mm seal tail and a closure with a plastic insert (an internal block that clamps the seal) made of Delrin, a strong plastic that replaces metal. The seal is made of HDPE and is resistant to temperatures from -40 to +80°C.

Applications:

trucks
drums
couplings

An MPT seal is used for closures that need to stay properly sealed, but also need to be openable without tools. Thanks to the 12 kg breaking strength, the seal stays in place during normal use and transport.

The MPT is often used in situations where an HPT is too strong and an LPT too weak. The seal offers a balance between sturdiness and ease of use.

Typical applications:

truck doors
drums and containers
technical couplings

An MPT seal has a breaking strength of 12 kg. This means the seal can be broken by hand with some force, but doesn't come loose easily during normal use.

The 2.8 mm seal tail and the strong plastic closure ensure the seal doesn't come loose easily during use. This makes the MPT stronger than a 6 to 7 kg LPT and less strong than a 22 kg HPT.

Comparison:

LPT: 6 to 7 kg
MPT: 12 kg
HPT: 22 kg

You choose an MPT seal when an HPT is too strong and an LPT comes loose too easily. The MPT is suitable when the seal needs to stay in place during use, but also needs to be removable without tools.

The MPT is used in applications that are checked or opened regularly, without the seal breaking immediately under light load.

Typical situations:

trucks checked on arrival
drums that are temporarily sealed
couplings that need to be loosened regularly

An MPT seal fits through small openings thanks to its 2.8 mm diameter. The thin, flexible seal tail makes it possible to insert the seal through narrow closures.

This matters for applications such as truck doors and couplings, where there's limited space to apply a seal.
