ProSeel®

As the largest manufacturer of gaskets in Singapore, Tat Lee prides ourselves on our highly personalised services. Our PROSEEL gaskets have been effectively used for more than a decade in various plants and applications in Singapore and the region, and can be made to order according to our customers’ specifications. We are also able to recommend solutions according to your needs.

Kammprofile Gasket

The Kammprofile gasket is a two-part seal compromising a precision-engineered grooved metal core and a soft sealing material bonded to either side of the core. The metal core can withstand high pressure loading while providing excellent deformation and sealing properties. Meanwhile, the soft sealing material fills any surface irregularity on the flange even at low bolt loads. The Kammprofile gasket is easy to handle and fit, and combines the benefits of hard and soft sealing technologies for a lasting seal that offers outstanding levels of gas tightness and joint integrity. The gasket has an unlimited shelf life and can also prolong the use of damaged or rotated flanges.

Spiral Wound Gasket

Renowned for providing remarkable seal quality under the harshest conditions, the spiral wound gasket seals flanges where temperature, pressure or flow rates demand high flexibility. A spiral of alternate metal strips and a softer filler material mean that the spiral wound gasket offers both good structural support and an excellent seal even with imperfect flange faces. Spiral wound gaskets are available in a variety of metals and materials – allowing for a wide range of structural densities – according to the demands of each application.

Ring Type Joint Gasket

The ring type joint is designed to last in high pressure applications. It is a precision-engineered solid metal gasket that forms a metal-to-metal seal with flanges. The gasket cross-section is designed to concentrate the bolt load over a small area in order to produce a high seating stress. The ‘RX’ and ‘BX’ gaskets are designed to be pressure activated which improves the efficiency of the seal as the internal pressure of the system increases.

Prolas™

PROLAS recyclable flange gaskets for fluid delivery

• Superior long term sealing performance
• Drinking water safe (NSF) for potable water delivery
• Current rubber EPDM material is “single use”, generates rubber waste at end of life à Replaced PROLAS gaskets are collected back and recycled into new gasket production
• High level of production waste (30%) during gasket cutting process that is disposed à Production waste from PROLAS gaskets can be recycled in-house

Frenzelit®

Prolas

We are proud to partner Frenzelit GMBH, a leader in innovative gasket materials for more than a century, combining innovative ideas with proven products to always find the right solutions for our customers. A variety of high-quality gasket materials are used to meet our customer’s requirements, such as fiber gaskets, graphite gaskets, high-temperature mica gaskets, PTFE gaskets.

novapress® Universal (PS 8900)

The balanced raw material combination consisting of high-quality aramide fibres and special functional fillers bonded with nitrile butadiene rubber (NBR), gives novapress® Universal the following special properties:

- Good tensile strength
- Excellent stress relaxation
- Very low gas leakage
- Very good oil resistance

Identification colour: green

novapress® Basic (PS 8800 /ZW 8800)

The balanced raw material combination, consisting of high-quality aramide fibres, special fillers and nitrile-butadiene-rubber (NBR), gives novapress BASIC the following special properties:

- Good media resistance
- Good stress relaxation
- High pressure resistance
- Excellent value for money

Identification colour: orange

novaphit® SSTC (PS 6600)

The TUV-certified solution for oval closure lid gaskets.

This gasket, which is based on the classic novaphit® SSTC material, has become the widely used standard product for oval gaskets that require official approval since TUV testing was introduced in connection with TRD 401.

Novaphit® SSTCTRD 401 satisfies the requirements made in the highest testing category D(250 °C/40 bar) specified in TRD 401 without any difficulty. It can, however, also be used when the application parameters are more demanding than this (see the application recommendation below). Oval gaskets 2,4 or 6 mm thick are produced from the basic material, which is 2 mm thick, by certified manufacturers. This means that all the different applications are covered - from delivery of a new boiler to a steam generator that has already been in operation for a long time.

Thanks to a sufficiently thick graphite layer and the positive properties of the expanded metal insert, novaphit®® SSTCTRD 401 is unusually adaptable to sealing surface unevenness.
Optimum advantage is taken of the low bolting forces required in the closure lid area due to the design parameters to shape the graphite.

Novaphit® SSTCTRD 401 also has all the properties of Novaphit® SSTC and can therefore be recommended for any other steam generation application too.
