Spring-Loaded Seal Solutions for Nordson® 1071968

Hot melt gun performance often fails at one small point: the internal spring-loaded seal. For systems using the Nordson® 1071968 “seal, spring”, leakage, stringing, or short service life usually mean this seal is worn or no longer properly energized.

XHH Seals manufactures spring-energized seals for these applications, giving you a stable, cost-effective alternative supply.

Nordson® and all OEM part numbers are used for identification only. XHH is an independent manufacturer.

What Customers Using 1071968 Actually Need

If your maintenance records show P/N 1071968 – SEAL, SPRING, you typically face one or more of these issues:

• Dripping / drooling from the nozzle when the gun is closed
• Stringing and poor cut-off at fast cycle rates
• Adhesive bypass into the air side of the module
• Very short rebuild intervals for H200 / CF-type modules

In all these cases, the root cause is usually the spring seal around the needle/shaft losing its preload or being chemically/thermally damaged.

XHH focuses on rebuilding this function, not just selling a “look-alike” part.

XHH Spring-Energized Seal for 1071968-Type Applications

Based on your samples or drawings, we design and manufacture a spring-energized PTFE seal that:

• Matches the critical dimensions of your existing 1071968-type spring seal
• Uses high-performance PTFE (or filled PTFE) suitable for hot melt adhesive service
• Integrates a corrosion-resistant metal spring to maintain constant sealing load
• Works both as a dynamic seal on the needle and a static seal in standby

You can use our seal:

• In original Nordson® modules that specify a “seal, spring” of this size
• In H200 / H200CF style replacement modules, such as third-party modules similar to G100 / G100F
• In custom hot melt heads where a spring-loaded PTFE seal is required

We do not claim a 1:1 OEM part number copy；instead we provide a functionally compatible spring-energized seal engineered to your data.

Relation to H200 / 144906 / G100-015 Style Modules

Many production lines that use 1071968-type spring seals also run:

• H200 / H200CF modules (for example, modules designated as 144906)
• Third-party replacement modules such as G100 / G100F series, where parts like G100-015 “Seal Spring Loaded” are used as internal seals for Nordson® H200 modules

XHH can manufacture compatible spring-energized seals for these module types based on your actual samples or drawings.

All OEM and third-party numbers mentioned here(1071968, 144906, G100-015, etc.) are used for identification and compatibility reference only. Final confirmation must follow your own BOM and maintenance documentation.

What Information We Need to Help You Quickly

To recommend a suitable spring-energized seal and quote efficiently, please send:

1. Part/module reference

• Seal part number (e.g., 1071968, or your internal P/N)
• Module type (H200, H200CF, CF-200, or G100/G100F style module)

2. Sample or drawing

• Used or new sample of the spring seal
• Or a drawing with inner/outer diameter, height, groove size, and shaft size

3. Operating conditions

• Adhesive type (EVA, polyamide, PUR, etc.)
• Normal working temperature and line speed
• Expected rebuild interval

With this information, our engineers can match or upgrade the seal design for longer life and more stable operation.
