Series LF05
Mini Water Hammer Arrestors
Sizes:
3
⁄8" –
3
⁄4"
The LF05 Water Hammer Arrestors are designed to eliminate
water hammer. The LF05 features Lead Free* construction to
comply with Lead Free* requirements.
Dishwashers, clothes washers, fast closing positive shutoff valves
incorporated in the plumbing system all contribute to creating water
hammer which is not only annoying but damaging to pipes and
appliances. Series LF05 water hammer arrestors provide economical
and effective single fixture protection from the destructive and annoy-
ing problem of water pressure shock. Utilizing piston style construc-
tion, factory charged and sealed, the Series LF05 provides automatic,
repetitive control of water hammer when properly installed.

• May be installed in new or existing plumbing systems vertically,
horizontally or at any angle
