Sealtek®’s range also includes industrial maintenance and repair product and other sealing devices, such as gland packings and flat gaskets.

Gasketing sheet in pure graphite, in sandwich structure, made of an expanded pure graphite central core, lined on both sides by aluminium foil. It represents the ultimate recent innovation in

Inside wear parts made in silicon carbide for enhanced abrasion resistance. Available as stand-alone item, or as part of a fully assembled API Plan 31 or 41.

Although extremely economical, this model is capable of covering the large majority of applications where high temperatures or pressures are not involved. Available with internal magnetic driven pump for improved

Ideal for all applications requiring that the fluid pumped should not come in contact with any metal seal parts. Based on advanced “full solid” technology manufacturing method, this seal can

Asbestos free gasketing sheet, ma-de of aramydic fibers, Rockwool fibers, and elastomeric NBR binders. Realized as standard material for a wide range of applications in ali industries. Excellent tensile strength,

The SEALTEK Style 410 seal can be used in applications with highly corrosive chemicals such as active organic compounds, strong oxidizing and reducing agents, concentrated acids and salts. The seal

Compressed sheet material made by aramid fibre with NBR rubber and special inorganic fillers. Due to its high aramid fibers content, it achieves excellent thermal values and the material features

Gasketing sheet manufactured with an innovative System which reinforces pure compressed graphite with aramydic fibres and very low quantity of elastomeric binder. The high flexibility, the mechanical strength and the

This seal represents the best alternative where a price/quality factor is critical. Without a dynamic O-Ring sealing of the shaf, it guarantees no fretting while the seal’s narrow cross section

Designed for installation in machinery operating according to EN 12756-L1K standard. The rubber bellows is supported by a metal body, enabling the seal to operate in particularly heavy fluid applications

STYLE 523 Carbon B/FKM/AISI 316/AISI 316 with Style 124 seat Q2 SiC/FKM

Very popular, widely used, high volume, low priced seals. The large self-cleaning spring is dependant on shaft rotation, which has to be specified when ordering. Suitable for most medium level

Rotary pusher type mechanical seal with cylindrical heavy duty spring. The open design of the spring avoids accumulation of solids, the flexible drive tolerates shaft misalignment and keeps always faces

This seal represents an important tool for maintenance as well as an indispensable component for the OEM in manufacturing of modern centrifugal pumps. Hydraulically balanced, the seal incorporates a full

Ideal solution in stuffing boxes with limited space, where Style 550 could not fit. Style 551 conforms with the EN 12765 L1K lenght requirements, which enables it to be easily

Sealtek Style 557 mechanical seal is the ideal solution for plan standardization, thanks to its interchangeable faces and the bidirectionality of its wave springs which guarantee the best possible operating

Pusher type rotating seal with a PTFE wedge sealing on the shaft. This PTFE wedge retains the sealed fluid and follows the seal movement to compensate for shaft run-out and

Available with Hastelloy C276 bellows and retainer (Style 581) Available with AISI 316 retainer and Hastelloy C bellows (Style 582).

Metal bellows rotary component seal, for high temperature or cryogenic applications. Secondary seals in graphite. Available with driving pin and double ply bellows for higher pressure resistance (Style 591)

Style 600NMT is a more efficient and more effective alternative to exotic alloys such as Super Duplex or Hastelloy C276, which are drastically outperformed by this revolutionary design where the
