Our seals are interchangeable with Vulcan type 1677 and type 1677M.
Sinusoidal wave spring and 'O'-Ring mounted seal.
Type 1677: Stainless steel head retainer and inserted face
Type 1677M: Monolithic head (optimal heat dissipation)
Both are stocked as a standard assembly with anti-rotational Type 8 DIN LONG 'O'-Ring stationary face.
The one-piece double wave spring provides superior strength and reliability compared to welded multiple-part wave springs which are prone to breakage under pressure.
Commonly used in chemical process industries.
