  • T-4355NL model rated for potable water systems
  • New condition ensures clean, undamaged threads for leak-free installation

1" No-Lead Bronze Coupling

The Legend Valve 313-175NL couples a 1" CTS compression end to a female NPT thread. It is built from no-lead bronze for potable-water service. The fitting suits residential and commercial plumbing crews needing a compliant transition. California Proposition 65 warnings apply to this product.

Compression Joint Under Pressure

The compression nut and ferrule seal on the tubing outside diameter when tightened to the manufacturer's torque. No-lead bronze resists dezincification and stress-corrosion cracking in aggressive water chemistries. The joint holds rated pressure without soldering or threading the tube. Repeated thermal cycles do not degrade the mechanical grip.

Replaces Leaded Brass Sweat Fittings

This coupling replaces leaded-brass sweat adapters where codes now forbid lead content. The jump is worth it on retrofit jobs where soldering access is limited or fire-risk rules ban open flame. It also avoids the cost and delay of threading copper tube in the field. Buyers who need a sweat-to-sweat connection or a different tube size must choose another fitting.

Questions about this item

Does the 1" T-4355NL coupling generate noise or heat when water runs through it all day?

This brass fitting has no moving parts, so it produces no noise or heat during continuous water flow.

What pipe type must I already have for the compression end to seal on this 1" T-4355NL coupling?

The compression side is made for 1" CTS tubing, so you need copper, CPVC or PEX with a compatible stiffener already installed.

Will the 1" T-4355NL no-lead bronze coupling thread onto older iron pipe threads without leaking?

The FNPT end follows standard NPT taper, so it mates with existing iron or brass male threads when sealed with tape or paste.
