Plumbing nipple for drain connections

The Legend Valve 311-145 is a no-lead red brass nipple sized at 1-1/2" x 3-1/2" for use in plumbing drain and trap assemblies. It provides a straight threaded connection between fittings in residential or commercial waste systems. The component is supplied new and meets the material requirements for potable water contact where local codes permit.

Consistent flow under continuous drainage

Brass construction resists internal corrosion from standing water and common drain chemicals, maintaining a smooth bore over extended service. The alloy does not degrade when exposed to temperature fluctuations typical in waste lines, so flow capacity remains stable during sustained discharge from fixtures or appliances. No internal coatings or liners are present to wear away under heavy use.

Red brass body with tapered pipe threads

The nipple is machined from no-lead red brass, offering durability against mechanical stress during installation and thermal cycling in service. Tapered NPT threads on both ends create a metal-to-metal seal when tightened, reducing reliance on excessive thread sealant. California Proposition 65 notices apply because the alloy contains listed chemicals; installers should follow local handling and disposal guidelines.

Questions about this item

Does the 311-145 brass nipple generate heat or noise during continuous water flow?

The brass nipple is a passive fitting with no moving parts, so it produces no operational noise or heat regardless of how long water runs through it.

What pipe threads must my existing plumbing have to connect this 1-1/2 inch nipple?

Your supply or drain lines need matching 1-1/2 inch NPT threads; the nipple itself has male threads on both ends for a direct joint.

Will the no-lead red brass alloy of the 311-145 react with older copper or galvanised pipes I keep in place?

Red brass is compatible with copper and galvanised steel; use a suitable thread sealant to prevent galvanic corrosion at the joints.
