No. F4 (904) Jumbo Wavy Closed Rose Piping Tip — Seamless 304 Stainless Steel XXL Decorating Nozzle
The Willia No. F4 (also designated as model 904) is an extra-large jumbo closed rose decorating nozzle designed for high-end bakeries, pastry studios, and culinary manufacturers. Distinguished by its specialized 8-ray curved zigzag crown, this nozzle creates deeply textured, architectural 3D rosettes, ruffled wave borders, and dramatic single-squeeze Zephyr swirls with crisp definition. Precision-drawn from heavy-gauge food-grade 304 stainless steel in a seamless one-piece construction, the F4/904 tip withstands high extrusion pressures without flexing or seam splitting. Direct from our Yangjiang manufacturing plant, we provide low-MOQ factory wholesale starting from 100 pcs, with custom laser branding and private label retail blister packaging from 500 pcs.

- One-Piece Seamless Drawn Construction: Completely seamless interior eliminates frosting hang-up and prevents bacterial accumulation.
- Heavy-Gauge 304 Stainless Steel: Solid corrosion-resistant food-grade steel delivers lasting durability through thousands of commercial dishwashing cycles.

- Ultra-Clean Release: Machine-finished edges ensure sharp petal cut-offs without ragged icing strings.
Frequently Asked Questions (FAQ)
Q: What is the primary difference between F4 (904) and standard closed star tips?
A: Standard closed star tips have straight, sharp cuts that produce classic rosettes. The F4 (904) features curved, wavy zigzag edges that introduce an undulating wave texture to each petal, giving flowers an organic, ruffled 3D look.
Q: Does this nozzle require a special coupler?
A: Because of its XXL jumbo base, the F4 tip is typically inserted directly into standard 14-inch or 16-inch pastry bags without a coupler, or paired with extra-large jumbo couplers.
Q: Can we request custom laser-engraved sizing and brand logos?
A: Yes. Starting from 500 pcs, we provide permanent fiber-laser logo and model number engraving on the outer collar of the nozzle.
