Industrial Gaskets
Gasket is a packing designed for inclusion between rigid mating parts in essentially stationary relationship to prevent leakage. They are found in flange joints, machine and process plant assemblies. Gaskets are produced in various shapes, sizes, ratings and designs out of different materials for the medium to be contained.
Gaskets are categorized as Metallic, Semi-Metallic and Non-Metallic (Soft) gaskets and each serves a different and specialized purposes. Our gaskets are made according to ASME, DIN, JPI, JIS, BS and API standards.
Gasket Types
Camprofile or Kammprofile Gaskets are also known as Grooved Gaskets due to its physical appearance where a solid corrugated core is covered by a flexible layer of graphite, Teflon® or other materials. This gasket type provides an extremely tight seal and is known for their long-term reliability hence can be normally found among older seals or flanges.
PTT also manufactures heat exchanger gaskets like metal jacketed gaskets, & camprofile. Camprofile gasket is becoming more & more popular in process plants nowadays. Traditionally, grooving of metal grooved gasket is done by large lathe machine. Today, with our special designed machine, we can produce camprofile gaskets up to 3000 mm in diameter at a much reduced production time.
Stands for Compressed Non-Asbestos Fiber. This is categorized under non-metallic (soft) gaskets; this type of gasket is also very common. This is a substitute to Asbestos based material, minus the health hazard and is safe for both handling and disposals. Typically produced in sheet form and shapes will be cut-out according to the desired dimensions.
PTFE is Teflon® and like graphite, it is an excellent sealing material and is relatively economical.
This type of gaskets offers a wide range of applications and the ease of both handling and cutting and is often conomical to produce.
We source our CNAF and PTFE gasket sheets from reputable companies such as Valqua (Japan) and Klinger (UK).
This gasket usually made from soft metal and rather simple to fabricate and is very economical where the only material needed for producing this type of gasket is rolled metal sheets or metal strips. With the aid of our latest laser cutting machine the metal sheets will be laser-cut to certain dimensions or is cut into segments and to be weld-joint for a larger diameter gasket.
Commonly used in heat exchangers. These gaskets are constructed with filler enveloped partially or fully by metal sheets. Among the material used for fillers are:
- Non – Asbestos
- Flexible Graphite
- Teflon
- Ceramic
Metal jacketed gaskets provides the best of both worlds, combining temperature resisting property of a metal jacket and sealing property of a soft filler, this type of gaskets are easy to fabricate and is also considered economical and suitable for irregular surface and flanges faces.
SWG Gaskets are widely used in the petrochemical, Oil and Gas industries and consists of a metal ring, graphite filler and steel strips that overlaps the filler and held together with a V-Shaped groove. SPW Gaskets are known for their superior sealing performance and is applicable for a wide range of joints and flange faces.
With our latest machine we are able to produce spiral wound gaskets to the finest quality and exacting standards and gaskets with superior sealing compatibility. We can make non standard SWGs sizes from 500 mm up to 4000 mm with thickness of the most common 4.5 as well as 6.5 & 7.2 mm.
Types of Spiral Wound gaskets are:
There are a few variations to these as well, depending on the desired application, some would be with or without the inner-ring and some would have ribs which are to suit Heat Exchangers. We have standard sizes in stock as well, wrapped and ready to be delivered.

In 1996, we expanded into material supply, providing gaskets, filtration products, valves, and other mechanical products.
Dissatisfied with the quality of gaskets received, we decided to design and produce our own gaskets here in Bintulu. Today, we proudly manufacture “tOgap® gaskets” and collaborate closely with renowned gasket makers to ensure the highest quality. We have become a key player supporting industries in Bintulu and beyond.
