TES Teflon® Encapsulated Seals – OEM Replacement Plates & Rings for Nordson-Compatible Melters

Replacement Teflon® Encapsulated Silicone (TES) plates and ring seals integrate a resilient silicone core with a fluoropolymer (FEP or PFA) Teflon® outer layer to deliver outstanding chemical resistance, high‑temperature stability, and low friction for leak‑free performance in melt‑adhesive equipment. Designed for Nordson roll and barrel melters—including BM200, VD200, DD200, 5506, 5550, Durapail, Versapail, and 506 series—these replacement seals meet exact OEM dimensions and tolerances while offering significant cost savings.

Overview: TES Seals for Compatible with Nordson® Melters

What Are Teflon® Encapsulated Silicone (TES) Seals?

TES seals feature a core made of silicone (VMQ) or Viton® (FKM), fully enclosed in a thin Teflon® shell—either FEP or PFA. This hybrid design provides the elasticity of elastomers and the chemical inertness of Teflon®, delivering long-lasting sealing even under extreme thermal and chemical exposure.

Key Features of TES Seals

Chemical Inertness: Teflon® encapsulation is virtually impervious to most acids, bases, and solvents, preventing core exposure and seal failure.

Temperature Range: Effective from –60 °C to +200 °C (VMQ core) or higher with FKM/Viton® cores, maintaining seal integrity under continuous heat.

Low Friction & Non‑Stick: Smooth Teflon® outer surface minimizes wear and material buildup, reducing operating torque and sticking.

Compression Set Resistance: Encapsulation prevents extrusion and compression set, extending seal life under dynamic loads.

Frequently Asked Questions

Q1: Are these seals a direct replacement for Nordson OEM parts?
A: Yes, our TES Plate and Ring Seals are designed to meet the dimensions and performance of Nordson OEM components.

Q2: How long do TES seals typically last in melters?
A: Service life depends on temperature, adhesive type, and usage cycles. Under standard operating conditions, users can expect 6–12 months of reliable performance before replacement is needed.

Q3: Can these TES seals be reused after maintenance or cleaning?
A: We do not recommend reusing TES seals once removed. Their sealing performance may be compromised after thermal cycling or compression set.

Q4: What's the lead time for custom orders?
A: Custom sizes or materials typically require 10–15 business days, depending on complexity.
