Thermoseal WaterSIL

WaterSIL is a universal high-pressure gasket material that is certified to NSF 61 and meets strict chemical leaching requirements.

Specially formulated compressed gasket material based on NBR and aramid fiber, Thermoseal WaterSIL is a universal high-pressure gasket material that is certified to NSF 61 and meets strict chemical leaching requirements.

Applications: NSF/ANSI 61 certified gasket material for use in potable drinking water systems and fixtures for public drinking water, food and beverage, hospitality and plumbing supplies.

Benefits of Products Certified to NSP/ANSI 61 Drinking Water System Components

Potable water systems have miles of piping and other devices such as pumps, meters and valves. All of these components require gaskets. Gasket materials certified to NSF/ANSI 61 ensure the safe passing of water on its journey to the consumer’s tap.

NSF/ANSI 61 establishes minimum health effect requirements for the chemical contaminants and impurities that are directly imparted to drinking water systems. It also determines what contaminants may migrate or leach into drinking water and confirms that they are below the maximum levels allowed to be considered safe. Market leaders strive to attain NSF certification as a mark of distinction that assures their product does not leach harmful contaminants or impurities into drinking water.

Certification to NSF/ANSI 61 ensures that the product meets the Safe Drinking Water Act requirements that protect public drinking water supplies in the US. NSF/ANSI 61 certification can often meet or fulfill the testing requirements for many other countries as well.

THERMOSEAL WaterSIL is specifically formulated to meet the NSF/ANSI 61 standard for sealing materials. It also has excellent dielectric strength properties. The dielectric strength is the maximum working voltage a material can withstand without breaking down, thus limiting corrosion in pipeline systems.

Look for the THERMOSEAL WaterSIL logo and NSF mark on the packaging to ensure your gasket material complies with NSF/ANSI 61 – Drinking Water System Components – Health Effects.

Form-in-Place Sealex® Joint Sealant

Sealex®Sealex® joint sealant, specially processed, 100% pure PTFE on a roll, provides soft, highly compressible gasketing for longer life and trouble-free sealing. Its form-in-place versatility also cuts maintenance and storage costs. The high compressibility of Sealex® enables it to effectively fill flange imperfections for a tight, leak-free seal. Under pressure, it provides a very wide, thin ribbon-like joint sealant. Unlike conventional PTFE which is prone to cold flow, Sealex® has good creep resistance and bolt torque retention properties.

Sealex® joint sealant does not support bacterial growth or cause product contamination and is FDA compliant. It has virtually no shelf-life concerns since PTFE is unaffected by normal environmental conditions.

It has excellent resistance properties to chemical attack. It is ideal for most chemical services at temperatures to 500°F (260°C) and pressure to 2,000 psi (138 bar). It is also suitable for cryogenic use to -321°F (-196°C).

KLINGERSIL® C-7400 Isolation Gaskets

Application Overview:

Some applications in plants call out for isolation kits to maintain the integrity and reliability of a pipeline and piping system. Isolation kits are designed to work in conjunction with flanges, gaskets, and/or bolt sleeves and washers by eliminating metal-to-metal contact and halting static electric currents. At times they are relied upon for critical applications in severe temperatures and conditions.

KLINGERSIL C-7400 - Isolation Gaskets replace Isolation Kits

The Problem: 

Industry’s first choice are phenolic gaskets. They are often supplied in kits, but they are hard and typically take a lot of load to seal. And lack of load is the number one reason for gasket failure.
