Gaskets

Staitech stock a wide range of gaskets in several FDA and USP class VI compliant materials in sizes up to 12”. In addition to standard gaskets, orifice plate and mesh screen gaskets are also available.

The gasket range includes:

• Standard gaskets
• High performance gaskets
• Orifice plate gaskets
• Mesh and perforated screen gaskets
• Sock screen gaskets
• Ported gasket system

Plain Gaskets

Staitech offer plain gaskets in several FDA and USP Class VI compliant materials such as EPDM, Viton and Silicone. Gaskets are also available in a number of high performance materials which address typical gasket issues such as creep, bore intrusion and ineffective sealing caused by thermal cycling in steam and hot WFI systems.

Orifice Plate Gaskets

Orifice plate gaskets are available both tabbed and non-tabbed. Slit gaskets allow easy removal of a solid inner disc for drilling or routine gasket replacement. All gasket elastomers are FDA CFR 21 compliant and meet UPS Class VI criteria. Where drainability is to be ensured, a conical plate design in available.

Tabbed Orifice Plate Gaskets

Where identification is required that an orifice plate is fitted then tabbed units are available. A slit gasket once again allows easy removal of a solid inner disc for drilling or routine gasket replacement. All gaskets are FDA CFR 21 compliant and meet USP Class VI criteria.

One Piece Orifice Gaskets

A range of solid orifice plates are also available in PTFE and PTFE infused stainless steel. Both plate types are FDA CFR 21 and USP Class VI compliant. As with all orifice types, plates can be drilled on site or prior to delivery.

Mesh Screen Gaskets

Mesh screen gaskets are available to suit 1/2″ to 4″ clamp fittings in accordance with ASME BPE dimensions. Three standard stainless steel mesh sizes are offered, with alternative sizes also available. All gasket elastomer’s are FDA CFR 21 compliant and meet USP Class VI criteria.

Sock Screen Gaskets

Sock screen gaskets are available in sizes 1-1/2″ to 4″ with two lengths of 16 mesh stainless steel screen. Sock screen gaskets are intended for applications where a large debris holding capacity is required. To aid installation and removal, Staitech also offer clamp ended spools matched to the two lengths of sock screen gaskets available. Sock screen gasket elastomers are FDA CFR 21 and USP Class VI compliant.

Perforated Plate Gaskets

Perforated stainless steel plates are available for use with the range of plain orifice plate slit gaskets offered by Staitech. Perforated plates are available in 316L stainless steel with a number of alternative hole sizes.

Thermocouple Gaskets

Where thermocouple wire is to be used for temperature mapping, Staitech offer standard gaskets cross drilled to allow the insertion of a single 1/0.2mm welded tip thermocouple wire. All gaskets are FDA CFR 21 and USP Class VI compliant.

Ported Gasket System

A ‘Ported Gasket’ takes the place of a standard gasket and allows insertion through its side wall of thermocouple instruments, thermometers and sample devices. All gaskets are FDA CFR 21 and USP Class VI compliant. Being 1mm thicker than a standard gasket, a modified clamp must be used when fitting a ported gasket. Gaskets are available with either 1,2,3 or 4 ports.

Flange Gaskets and O-rings

For sanitary applications where flanges are used, Staitech offer a range of cut gaskets and sheet gasket materials. Available materials include PTFE, Gylon, EPDM, Viton and Silicone. Staitech also stock a wide range of FDA CFR 21 and USP Class VI certified O-rings in EPDM, Viton, Silicone and FEP encapsulated materials. For non-standard sizes Staitech also offer a bespoke moulding service. Speak to us for pricing and availability.

Diaphragm Guard Gaskets

Diaphragm guard gaskets combine a standard outer seal with offset micro-membrane. This membrane protects the gauge or instrument diaphragm from aggressive system medi or cleaning solutions whilst having negligible effect on the instrument accuracy. Diaphragm guard gaskets are available in EPDM, Viton, Platinum cured Silicone and PTFE; all of which are FDA and USP Class VI compliant.
