PTFE Teflon Gasket Construction

The J27903 gasket is made from PTFE, a fluoropolymer widely used for sealing components in chemical-handling equipment. PTFE offers resistance to many industrial chemicals, although suitability depends on the specific fluid, concentration, temperature and operating conditions.

Its construction provides a replacement sealing component for compatible Chem-Tech pump valve connections where the manufacturer specifies a TFE gasket.

Chem-Tech Pump Compatibility

Pulsafeeder replacement parts documentation identifies J27903 in Chem-Tech Series 100, 150 and 200 parts schedules. Distributor listings additionally reference compatible Series 100D and 150D mechanical diaphragm pump configurations.

Potential compatible applications include:

• Chem-Tech Series 100 chemical metering pumps
• Chem-Tech Series 150 chemical metering pumps
• Chem-Tech Series 200 chemical metering pumps
• Compatible Chem-Tech 100D and 150D configurations
• Liquid-end valve connection maintenance
• Replacement of worn or damaged PTFE sealing gaskets

Gasket Sealing Function

The Pulsafeeder J27903 PTFE gasket provides a sealing interface between designated mating components within compatible pump assemblies.

Correct gasket selection and installation help maintain the intended sealing arrangement and reduce the possibility of leakage at the connection. The gasket must match the original equipment dimensions and material requirements.

Chemical Metering Pump Maintenance

Gaskets should be inspected during pump servicing for deformation, cuts, surface damage, chemical deterioration and other conditions that could affect sealing.

Replacing damaged sealing components with correctly specified parts supports proper maintenance of the chemical metering pump liquid end.

Replacement Gasket Kits

The Pulsafeeder J61518 gasket kit is listed as containing four J27903 Teflon gaskets. Customers requiring multiple gaskets for maintenance may compare the individual J27903 component with the J61518 kit.

Compatibility and Installation

Before purchasing the Pulsafeeder J27903 Teflon gasket, verify the original part number, pump series, valve assembly configuration and chemical compatibility.

Confirm the gasket dimensions against the applicable manufacturer parts diagram. Depressurize and isolate the chemical feed system before servicing the pump.

Follow Pulsafeeder installation and maintenance instructions when replacing liquid-end sealing components.
