Hygienic & High-Performance Seals for Pharmaceutical Applications

At Ashton Seals, we supply high-performance sealing solutions for the pharmaceutical industry, designed to meet strict hygiene, safety and regulatory requirements. From drug manufacturing and processing to sterile filling and packaging systems, our seals deliver contamination control, chemical resistance and long-term reliability in critical applications. 

Sealing Solutions for Pharmaceutical Systems

We provide sealing solutions for a wide range of pharmaceutical applications including:

  • Drug manufacturing and processing equipment
  • Clean room and sterile environments
  • Filling, dosing, and packaging systems
  • Bio pharmaceutical and laboratory equipment
  • Pumps, valves and fluid handling systems

 

These systems require precision-engineered seals that maintain purity and prevent contamination at every stage of production.

 

Hygiene, Clean room & Contamination Control

 In pharmaceutical manufacturing, maintaining absolute cleanliness and product integrity is essential.

 

Sealing solutions must:

  • Prevent ingress of contaminants and bacteria
  • Minimize particle generation and extractables
  • Be suitable for clean room environments
  • Withstand sterilization processes such as CIP (Clean-in-Place) and SIP (Steam-in-Place)

Failures in sealing can compromise product safety, making seal performance critical to compliance and patient safety.

Pharmaceutical Standards & Certifications

Sealing solutions used in pharmaceutical environments must meet strict global standards:

  • Key Pharmaceutical Certifications
  • FDA (Food & Drug Administration) – ensures material safety and suitability for contact applications
  • USP Class VI – highest standard for bio compatibility and low toxicity
  • EU Regulation 1935/2004 – materials in contact with consumables

 

Additional Requirements:

  • GMP (Good Manufacturing Practice) compliance
  • Full material traceability and documentation
  • Low extractables and leachables
  • Clean room manufacturing capabilities

 

These standards ensure sealing components are safe, compliant and suitable for pharmaceutical production environments.

Products for Pharmaceutical Applications

We supply a comprehensive range of sealing products for pharmaceutical systems including:

These products are widely used across processing equipment, sterile systems and fluid transfer applications.​

Materials & Performance

Pharmaceutical sealing solutions must be manufactured from materials that meet strict performance and compliance requirements.

We offer materials that provide:

  • Resistance to aggressive chemicals and cleaning agents
  • Compatibility with sterilization processes (CIP/SIP)
  • Low levels of extractables and contamination risk
  • Stability across temperature and pressure variations

Common materials include:

  • PTFE – excellent chemical resistance and purity
  • Silicone – widely used for bio compatibility and flexibility
  • EPDM – suitable for steam and sterilization processes
  • FFKM – high-performance material for extreme environments

 

These materials ensure reliable performance and compliance in sensitive pharmaceutical applications.

 

Typical Applications

Our sealing solutions are used across a wide range of pharmaceutical systems:

  • Tablet presses and processing equipment
  • Filling and packaging machines
  • Sterilizers and autoclaves
  • Pumps, valves, and fluid systems
  • Bio pharmaceutical and laboratory equipment

 

These applications require precision sealing to maintain product purity, process efficiency and regulatory compliance.
