  • Lead-free cast copper silicon alloy meets potable-water standards
  • 304 stainless-steel screen traps debris to protect downstream equipment
  • EPDM gasket seals reliably at 250 psi and 100 °F
  • Compact 2 3/4 in body fits tight plumbing runs
  • Suitable for beverage dispensers dental ice makers and instrument controls

In-Line V Strainer for 1/2" NPT Lines

The Watts LF27 installs directly into half-inch female NPT piping to trap debris before it reaches downstream equipment. Its copper silicon alloy body and 304 stainless steel screen handle potable water, beverage dispensers, dental lines and instrument control systems.

Practical Limits of 1/2" NPT Connection

The strainer is rated for 250 psi at 100 deg F, so pressure spikes above that level risk damaging the casting or gasket. The fixed 1/2 inch female threads cannot be adapted to larger pipe sizes without additional fittings that are not included.

Capacity and Headroom for Fine Filtration

The integral 304 stainless screen stops particles that would clog ice cube machines or control valves, while the EPDM gasket maintains a seal through normal thermal cycles. Flow restriction becomes noticeable once the screen loads heavily, requiring periodic removal and cleaning to restore full capacity.

Questions about this item

Should I choose the LF27 or another Watts strainer model for my 1/2-inch line?

The LF27 is built for 1/2-inch FNPT connections and 250 psi at 100 deg F, so match those two figures to your system requirements.

What does the 250 psi rating mean once the strainer is installed in a real machine?

It is the maximum working pressure at 100 deg F; the EPDM gasket and 304 stainless screen hold that pressure in beverage dispensers, dental units and ice makers.

How does the NPT interface limit what I can connect to the LF27?

Female NPT threads on both ends accept 1/2-inch male NPT pipe or fittings; the connection gender and size are fixed by the casting.
