Description Details
Restore the integrity and leak-free performance of your espresso machine's steam wand with the genuine Viton O-Ring, Swivel Wand 1,78X6,75 FKM 70 SH (Part # L171/2). This critical sealing component is engineered using high-performance FKM (Fluoroelastomer) rubber, commonly known by its brand name Viton, which offers superior resistance to the extreme temperatures and caustic chemical attack typical in steam and milk systems. If you're experiencing a "leaky steam wand when closed" or notice "steam escaping from the swivel joint," this OEM-specified O-ring is the precise solution to maintain a proper seal. Its primary feature is its 70 Shore Hardness (70 SH), ensuring durability and compression set resistance for maximum longevity in high-cycle, commercial settings.
This O-ring (1.78 x 6.75 mm dimensions) is specifically designed for the swivel mechanism on many commercial steam wands, providing smooth movement without compromising the seal. The core benefit of replacing old, degraded Buna or silicone rings with this Viton counterpart is the prevention of premature wear, ensuring your steam pressure remains consistent for perfect milk texturing. Usage involves carefully replacing the worn ring in the steam wand knuckle or swivel joint to immediately stop annoying drips and leaks. Don't let a "faulty swivel wand O-ring" impact your workflow; this small part is essential for reliable operation.
Investing in the Viton O-Ring L171/2 guarantees consistent, professional results and saves money on costly steam loss. It is an indispensable preventative maintenance item for any commercial espresso machine owner looking to solve "steam wand joint leaks" and prolong the life of their equipment.
