Industrial Tubing, Gaskets & Chemical Hoses
Certified Fluid Sealing Systems
Don’t just buy parts. Engineer zero-leak outcomes for corrosive, high-purity, and safety-critical service. Built for real plant conditions: chemical transfer, suction/discharge duty, and flange sealing where bolt load and surface reality matter.
Why System Integrity Wins
Problems don’t show up in the catalog. They show up at startup: seepage on the flange, chemical odor in the room, soft tubing at temperature, and hose fatigue on routing bends. The right selection accounts for chemistry, heat, pressure cycles, bolt load, and the actual surface condition.
1) Control Creep & Relaxation
Upgrading from commodity gasket materials prevents repeat retorque and chronic seepage.
2) Seal Mixed Flange Materials
Low-stress sealing helps protect plastics while still sealing steel under real bolt loads.
3) Specify Transfer Duty Correctly
Suction/discharge service demands the correct liner, reinforcement, and routing discipline.
“If it can leak, it eventually will — unless the seal design accounts for bolt load, surface condition, and real chemistry. We select components as a system so you don’t discover the weak link during startup.”
Three Core Families
Select the category that matches your service conditions, then request expert guidance for critical applications.
High-Purity Fluoropolymer Tubing (PFA & FEP)
For high-purity service where extractables, thermal margin, and stability matter.
GORE™ Industrial Gaskets & Flange Joint Sealant (ePTFE)
For chemical sealing, mixed flange materials, and low-bolt-load applications where reliability is non-negotiable.
Chemical Transfer Hoses (Acid • Suction • Discharge)
For aggressive media and demanding routing: liner compatibility, reinforcement, and safer installation.

Clear, practical guidance for selecting tubing, gaskets, flange joint sealant, and chemical transfer hose solutions.
What is the difference between CNAF and PTFE gaskets?
CNAF (Compressed Non-Asbestos Fiber) gaskets are a standard industrial seal but can harden and become brittle over time. PTFE (Polytetrafluoroethylene), specifically GORE™ ePTFE, provides superior chemical resistance (pH 0-14) and does not degrade, age, or cold flow, making it the safer choice for hazardous chemical sealing.
Is PTFE the same as Teflon?
Yes, Teflon™ is a brand name for the chemical compound PTFE (Polytetrafluoroethylene). However, Liberty CES supplies GORE™ Universal Pipe Gaskets, which use Expanded PTFE (ePTFE) to solve the "creep" and relaxation problems found in standard commodity PTFE sheets.
What is the best chemical hose for transferring acid?
For transferring aggressive acids (sulfuric, hydrochloric), we recommend a Cross-Linked Polyethylene (XLPE) or Ultra-High Molecular Weight Polyethylene (UHMW) chemical hose. For extreme purity and heat resistance, a PTFE-lined hose is the ultimate solution.
Can I use GORE Joint Sealant for concrete expansion joints?
No. GORE™ Joint Sealant is a specialized form-in-place gasket tape designed for sealing industrial piping flanges and equipment manways. It is not designed for concrete pavement or construction expansion joints.
