PRODUCT OVERVIEW

US-21: HOSE,FLEXIBLE.

"Nee-naw, Nee-naw" went the sound of the fire trucks as they raced through town, to put out this major residential fire. This graphic 45 piece puzzle demonstrates real-life heroes (firefighters) at work. 15 firefighters surround the building, attempting to put out the fires.

In this scenic and illustrative puzzle, you will find two large fire trucks, buildings side by side, a rescue helicopter hovering over the building, a dingy, a lady with a bucket full of water, water from hoses being sprayed on every floor, fire blazing from every window, a rescue dog with a helmet, two firemen in the dingy with a first aid kit, and grey smoke engulfing the skies. This puzzle is aimed at slightly older children who can use their visual skills to quickly identify the missing pieces. This part is cataloged in the U.S.

Government catalog under NSN 4720-00-483-0707, indicating validated use in U.S. government and defense logistics supply chains.

COMPONENT DIAGRAM
PIPE SECTION — SCHEDULE = WALL THICKNESS WALL: — OD: — LENGTH: — — — PN: US-21 · Larsen ⚠ VERIFY BEFORE ORDERING Schedule = wall thickness, NOT pipe diameter. Sch 40 and Sch 80 have the same OD but different wall thickness. Nominal pipe size ≠ actual OD — a 1" pipe is actually 1.315" OD ✓ BROKER TIP Sch 40 = standard wall, Sch 80 = heavy wall (higher pressure), Sch 160 = extra heavy. Seamless pipe is required for high-pressure applications — welded pipe has lower ratings PARTSTABLE TECHNICAL DRAWING — NOT TO SCALE
