Compare plumbing fittings and HVAC vents before choosing your size and pack quantity.

Plumbing fittings

Build your list around the fitting type, connection, nominal size, and pack quantity.

Connection type: Check whether you need a slip cap, threaded plug, straight coupling, or PEX-B female adapter. Match the listing to the connection on your existing system.
Nominal size: Select the size shown in the product options. Nominal pipe size is a product designation, not a measurement of the fitting's outside diameter.
Pack quantity: Compare single-item and multi-pack options. Check the selected pack quantity and price before adding it to your cart.
Compatibility: Confirm material, connection, and service suitability against the exact product's documentation. Ask for missing specifications before ordering.

Compare the vent style and included parts, then confirm dimensions for the selected model.

Cover only or plenum included: The linear slot diffuser cover family is cover-only; its plenum and installation hardware are sold separately. The plenum-combination family includes a vent cover and matching plenum.
Opening and face dimensions: Record your opening and required face dimensions separately. Check an exact-model drawing before treating a listed size as a cutout dimension.
Slot count and style: Compare one-, two-, and three-slot options. Trimless plaster-in registers are a different product family from linear slot diffusers.
Pack contents: Check whether the selected option is a single register or a four-pack. Confirm the required plenum, duct connection, and mounting parts for your project.
