Legend Valve 830-145C Composite Tubing Manifold Connector 3/4 in

SKU CH-3YD7-K960N

Composite tubing connects to a manifold in 3/4 inch size for plumbing systems

  • 3/4 in connector links composite tubing to manifold
  • Legend Valve brand supplies industrial plumbing equipment
  • New condition means full factory specification applies
  • Part number 830-145C identifies this specific fitting
  • California Proposition 65 warning notes chemical hazard awareness

Application and purpose

The Legend Valve 830-145C connects 3/4 inch composite tubing to a manifold in industrial plumbing installations. It is supplied as a connector pair for joining two tube runs. Professional installers and maintenance teams use it to create secure, leak-free junctions in fluid distribution systems. The component is designed for new-build and retrofit projects where composite tubing is specified.

Operational characteristics

The connector is manufactured from materials that meet industrial plumbing standards for pressure and temperature service. No moving parts or seals require periodic adjustment, so noise and vibration are not factors in normal operation. Power draw is not applicable to this passive fitting. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm, which installers should note during handling.

Upgrade context

This fitting replaces worn, corroded or incompatible manifold connectors on existing composite tubing networks. The jump is worth it when a system shows leakage at the manifold joint or when tubing material is changed and a matching connector is required. It is not suited for installations that demand a different tube diameter, thread standard or a single-connector configuration.

Questions about this item

How do I install the 830-145C connector onto 3/4 in composite tubing and what step is often missed?

Push the tubing fully onto the barbed end until it seats against the shoulder; the step often missed is not pushing far enough, which leaves a leak path.

What maintenance or replacement will the 830-145C connector need over time?

Inspect the barbed seal and tubing for cracking or hardening annually; replace the connector if the composite shows stress fractures or the seal weeps.

What limit appears first on the 830-145C connector during sustained pressure cycles?

The composite body can develop stress fractures at the barb root before the metal manifold threads show wear.
