The Heavy Duty Pull Tight Seal (HPT) can hardly be broken by hand (22 Kg) and is suitable for both indoor and outdoor use. The versatile HPT is available in three lengths and is stronger and longer compared to the Medium Duty Pull Tight seal (MPT) . The HPT is a versatile indicative plastic seal made of high-density polyethylene (HDPE). Due to this choice of material, this seal has a high breaking strength with a relatively thin seal tail and is resistant to extreme weather conditions. The high breaking strength is partly achieved by a tail diameter of 3.5 mm. This makes the seal suitable for sealing, among other things, trucks, train wagons and barrels. The seal is provided with the text “HPT SEALED” from stock. In addition to the stock product, it is possible to provide the Heavy Duty Pull Tight Seal with its own print in various colors.

Tough sealing in three lengths: 12 “(30cm), 15” (37.5cm) and 18 “(45cm)

The multifunctional Heavy Duty Pull Tight Seal is manufactured in three different lengths. The length of the seal is shown in inches. The seal was developed in the United States of America and is also produced there. The shortest version of the seal is the 12 inch version with a total length of 30 cm (usable length 26.5 cm). The middle version is the 15 inch with a total length of 37.5 cm (usage length 34.0 cm). The longest version is the 18 inch. This has a total length of no less than 45 cm (usage length 41.5 cm).

The length of the seal is stated in the imprint. The print on the 12 ”variant is for example“ HPT 12 SEALED ”. On the longest version, the number 18 can be read from the print.

Robust seal tail with a diameter of 3.5 mm and 22 kg breaking strength

The Heavy Duty Pull Tight Seal has a relatively thick seal tail. The diameter of the seal tail is namely 3.5 mm. Thanks to the strong plastic closing mechanism and the choice of material (PE), the seal has a breaking strength of 22 kg. This puts the seal in the category with a medium breaking strength. An example of a stronger seal is the Swift Seal with a breaking strength of 35 kg. Nippers are required to break this seal. The Medium Duty Pull Tight Seal is an example of a seal with a lower breaking strength of 15 kg, which is relatively easy to break by hand is.

Closing mechanism with patented plastic

The Heavy Duty Pull Tight Seal has a plastic insert made from Delrin®, a patented type of plastic. Delrin® is made from acetal (Polyoxymethylene POM). This material is used as a replacement for metal. The highly reliable material is extra strong and has a high temperature resistance from -40 to +120 degrees Celsius.

Hygiene and food safety

With seals with a metal insert it can happen that pieces of plastic come loose, because the plastic rubs / scrapes against the metal. This is not the case with a plastic insert. This property is especially important in the food and medical industry.

Hard-to-break seal made of HDPE

The seal is made of high-quality polyethylene with a high density (abbreviated to HDPE). The material is resistant to a large number of chemicals. The material can also be used in a wide range of temperature. The Heavy Duty Pull Tight Seal is resistant to temperatures from -40 to +80 degrees Celsius. In addition, this type of Polyethylene has a high stiffness and is therefore extra strong. Due to the choice of materials and the generous diameter of the seal tail, the seal can hardly be broken by hand.

Suitable for sealing, among other things, trucks, train wagons and barrels

Trucks and rail cars can be sealed with the Heavy Duty Pull Tight Seal. The high breaking strength of the seal ensures a safe closure of the cargo areas. Significant forces may be applied to the closure during transport.

The Heavy Duty Pull Tight Seal can also be used for sealing drums. The seal is resistant to chemical agents. In addition, the high breaking strength ensures a safe closure of the lid. This seal is often used in the chemical industry or in the food industry for closing a barrel of semi-finished product.

With unique printing and ascending numbering

Each Heavy Duty Pull Tight Seal has a unique print. The seal is provided from stock with the text “HPT SEALED”. This text, together with a one-off ge produced number a unique characteristic. Both Navacqs and the manufacturer of the seal ensure that each combination is only produced once. This, in combination with good registration, can prevent fraud and manipulation.

In addition to the stock product, it is possible to provide the Heavy Duty Pull Tight Seal with its own print in various colors. For example in the form of a company name or logo. Please contact us via +31 (0) 10-495 0000 or sales@navacqs.com to discuss the possibilities.
