PULSAtron L1100400-PVC PVC Coupling Nut for 1/2 Inch OD Tubing

The Pulsafeeder PULSAtron L1100400-PVC is a PVC replacement coupling nut for 1/2-inch outside-diameter tubing. This component is designed for compatible PULSAtron chemical metering pump tubing connection assemblies requiring the original equipment coupling nut specification.

Pulsafeeder replacement parts documentation identifies L1100400-PVC as COUPLING NUT 1/2" OD. The PVC material configuration distinguishes this component from other available coupling nut material options.

Distributor documentation lists this replacement fitting for selected PULSAtron Series A+, C, C+, E and E-DC pump configurations.

PVC Coupling Nut Construction

The L1100400-PVC coupling nut is identified as a PVC component. PVC is a thermoplastic material commonly used in compatible chemical feed equipment and fluid-handling fittings.

PVC offers resistance to many chemicals when selected for the appropriate process fluid, concentration, temperature and operating conditions.

Material compatibility must be confirmed before installation, particularly when the tubing connection is exposed to aggressive chemicals or elevated temperatures.

1/2-Inch OD Tubing Connection

The PULSAtron L1100400-PVC is specified for a 1/2-inch outside-diameter tubing connection.

The coupling nut is used with corresponding fitting components to help retain tubing in the intended connection assembly.

The 1/2-inch specification refers to the tubing outside diameter and should not be interpreted as the nut thread diameter or the tubing inside diameter.

PULSAtron Pump Compatibility

Distributor listings identify the L1100400-PVC as compatible with selected PULSAtron chemical metering pump configurations, including:

• PULSAtron Series A+
• PULSAtron Series C
• PULSAtron Series C+
• PULSAtron Series E
• PULSAtron Series E-DC

Compatibility depends on the specific pump model, liquid-end configuration and tubing connection size. Not every pump within these series necessarily uses a 1/2-inch coupling nut.

Chemical Metering Pump Applications

The L1100400-PVC replacement coupling nut is used in compatible chemical feed tubing connections.

Potential applications include:

• Industrial chemical metering pump maintenance
• Water treatment chemical dosing equipment
• Wastewater treatment chemical injection systems
• Compatible chemical feed tubing assemblies
• Replacement of cracked or damaged coupling nuts
• Maintenance of PULSAtron pump tubing fittings

Tubing Fitting Maintenance

Inspect the coupling nut during routine pump maintenance for cracks, deformation, damaged threads and chemical deterioration.

Check the associated tubing, fitting body and sealing components for damage or improper seating.

Replace worn or damaged coupling nuts with the correct manufacturer-specified component to maintain the original connection arrangement.

Compatibility and Installation

Before purchasing the Pulsafeeder PULSAtron L1100400-PVC, verify the original part number, tubing outside diameter, pump model and liquid-end fitting configuration.

Confirm that PVC is suitable for the chemical being pumped and the operating conditions.

Follow the applicable Pulsafeeder installation instructions. Isolate, drain and depressurize the chemical feed system before disconnecting or replacing tubing fittings.
