Lasco

Lasco plumbing repair parts and fittings cover faucet, toilet, drain and supply-connection jobs for homeowners and contractors. You can search the catalog by description, part number, UPC or manufacturer, giving you several ways to narrow down a replacement before comparing its fit.

Larsen Supply Company is the business behind the Lasco plumbing supply catalog. Its range includes repair parts, pipe and tubing, and flexible connectors. Faucet parts and toilet repair products sit alongside drain pipe fittings and plastic fittings.

Faucet and toilet repairs

For a faucet repair, start with the faucet maker and any identifying number on the old part. Lasco’s faucet-parts category and manufacturer search give you a starting point. Looking alike is a poor fit check because the stem, seal or attachment can differ. Compare those details on the replacement.

Lasco also has a toilet repair category. Work out where the trouble starts before choosing the part: water passing into the bowl and a tank that fills poorly call for different checks. Match the replacement to the tank’s connections and operating arrangement.

Keep the part number or UPC with the repair record. Either identifier works in the Lasco catalog when you need the same part again.

Drain, PVC and poly fitting jobs

Lasco’s catalog includes drain pipe fittings, metal pipe fittings and plastic fittings. Sort these by the service they’ll handle. A drain connection and a pressurized supply connection have different demands, so match each fitting to the service and the pipe it joins.

For LASCO-labeled PVC pressure fittings, verify the maker and the exact fitting’s material, size, connection type and pressure rating before choosing a cap, coupling or elbow.

The Lasco Poly quick-connect family includes female adapters, male adapters and reducing couplings. Choose the connection you need first, then match the tubing requirements for that exact fitting.

The nylon barb hose adapter connects poly tubing to a male garden-hose thread. Treat the two ends as separate fit checks: tubing inside diameter on one side and the mating hose thread on the other. Chemical compatibility needs its own check; keep this adapter out of systems carrying acid-based fertilizers, bromine, chlorine, fluorine, xylene or any acids.

Icemaker supply connections

Lasco’s braided stainless-steel icemaker supply line connects a water-supply valve to an icemaker and can connect to an inline filter. The line is 20 feet long, with female compression connections at both ends. Check both mating connections, then plan the route so the line stays clear of sharp edges and pinch points.

Frequently Asked Questions

How do I match Lasco PVC fittings to my pipe?

Match the pipe’s marked size to the fitting’s nominal size. Nominal size is a size designation, so measuring across the outside of the pipe won’t necessarily give you that number. You also need a connection that matches the pipe and a fitting rated for the job.

What does Schedule 40 mean on a Lasco PVC fitting?

Schedule 40 identifies a dimensional classification; it isn’t a working-pressure rating. You still need the exact fitting’s pressure and temperature limits before using it on a pressurized line. A schedule marking doesn’t make a drain fitting suitable for pressure service.

What is a Lasco PVC tee used for?

A tee adds a branch to a pipe run. Check the size at each opening before you choose one, because a tee can have a smaller branch connection. Where you use it also depends on whether the exact fitting is intended for drainage or pressure service.

What kinds of Lasco fittings are available for poly pipe?

Lasco’s Poly quick-connect family includes female adapters, male adapters and reducing couplings. For a garden-hose connection, the nylon barb adapter joins a 3/4-inch insert connection to a 3/4-inch male garden-hose thread and has a listed working pressure of 150 psi. You size the tubing for that barb by its inside diameter; that sizing rule shouldn’t be carried over to a quick-connect fitting without checking its tubing requirements.
