Easy-to-Apply, Versatile Joint Sealant

Flex-Tex Expanded PTFE Flex-tex expanded PTFE is your go-to sealant in maintenance, especially when emergencies come up. This flange sealant is a soft, compressible gasketing material made of 100% pure, expanded PTFE available with an adhesive strip for easy application. It comes in a number of forms, including ribbon, tape, or valve stem packing.

With “flex” in its name, you can be sure that this sealant will be flexible to your needs and industrial equipment. It is a form-in-place gasket that conforms to virtually any sealing surface. Flex-tex meets FDA requirements and offers guaranteed strength, resistant to common chemicals, and is rated for temperatures from -400°F to 550°F compared to any other soft gasket. Strength and durability is guaranteed in the Flex-tex joint sealant. Upon compression, it forms a thin, hard ribbon that fills in surface irregularities and creates an extremely tight seal. It has a high resistance to cold flow, unlike most “hard” sheet PTFE. Avoid downtime and seal-proof your manufacturing and facility equipment by using Flex-Tex sealant for your maintenance needs.

High Performance Flange Joint Sealant

Flex-Tex expanded PTFE Joint Sealant is an expanded virgin PTFE, manufactured in generally rectangular cross sections of widths from 1/8″ – 1″. The Joint Sealant has an adhesive backing and conforms to FDA requirements. Made of 100% PTFE, it is resistant to most common chemicals, and is rated for temperatures from -400°F to +550°F.

Flex-Tex can be used in just about any accessible bolted joint that features a flat or serrated sealing surface. It is easy to install and remove, making it a highly versatile and cost-effective solution for many demanding sealing applications.

Features:

  • Form-In-Place | conforms to any surface, including rough, pitted, scratched and damaged surfaces.
  • Flexible | can be installed on round, oval, rectangular and complex surfaces.
  • Chemically Resistant | made without fillers or binders, our 100% PTFE Joint Sealant exhibits the same chemical inertness of pure virgin PTFE.
  • Adhesive-Backed | convenient adhesive strip and peel-off backing allows for easy installation on both horizontal and vertical surfaces.
  • Unlimited Shelf Life | shows no age deterioration, and resists creep & cold flow.

Flex-Tex is the “Go to Sealant” for emergency situations and unexpected shut downs, often replacing standard ring gaskets. It should be part of every Maintenance Technicians tool box.

Installation

To install Flex-Tex Joint Sealant, follow these easy installation instructions. Proper assembly will result in a form-in-place, high-density gasket that conforms to the sealing surfaces and fills in surface voids and irregularities.

    1. Select a Joint Sealant width that is 1/3-1/2 of the flange sealing surface width. A guideline for round, 150# & 300# ANSI flanges is as follows:
Flange Size Joint Sealant Size
Up to 1/2″ 1/8″
3/4″ to 1-1/2″ 3/16″
2″ to 4″ 1/4″
5″ to 8″ 3/8″
10″ to 16″ 1/2″
18″ to 24″ 5/8″
24″ to 36″ 3/4″
36″ and above 1″

Clean seal surface of dirt, grease and all other forms of debris

  1. Measure and cut off a length of Joint Sealant that is several inches longer than the mean length of the seal surface. Joint ends must overlap.
  2. Remove the peel-off backing.
  3. As diagrammed below, beginning to the left of a bolt hole, apply Flex-Tex clock-wise to the flange surface inside the bolt hole circle, overlapping the ends in an “X” fashion.

Specifications & Instructions

5.Bolt up mating surfaces. Torque in a “star-type” pattern, and in steps, preferably 60%, 90%, and finally 100%. It may be necessary to make a repeat pass at 100% in the event some relaxation occurs.
