Your sanitary or ultra-pure system is unique, with special demands that can't always be met with routine "off-the-shelf" parts. That's why Top Line maintains a large selection of specialty gaskets, orifice plates and other problem-solving components. These parts feature the best materials, plus advanced designs based on decades of experience meeting the needs of industries like yours.

Screen Gaskets
Top Line Screen Gaskets are available with a variety of screen and gasket materials to suit every processing application. These screen gaskets can be used to remove large particles, protect pumps and valves, pre-filter solutions ahead of membrane filters, generate turbulence and more. Available in sizes from 1/2" to 4", our selection includes:

	Metallic screens:
	Type 304, 316 or 316L stainless steel Hastelloy Stainless steel perforated
	Non-Metallic screens:
	Polypropylene Teflon®
	Mesh sizes of 20 micron through 4 mesh
	Gasket materials:
	Viton® EPDM Platinum silicone Buna-N Teflon®

Orifice Plates
Designed to provide reliable flow reduction without deadlegs, our Orifice Plates include a self-draining design to avoid trapping product and bacteria. Constructed of type 316 stainless steel, these plates are available in sizes from mini to 4", with drilled holes from 1/64" to 1-1/2", and feature:

	Gasket materials in your choice of Viton®, Platinum Silicone, EPDM, Buna-N and Teflon®
	Compliance with USDA , 3A and ASME-BPE standards
	U.S. Pharmacopoeia Class IV-XXII certification

TEF-STEEL
Reduce the downtime of your sterilize-in-place (SIP) system with our new TEF-STEEL gaskets. Made from a 50/50 mixture of Teflon and type 316L stainless steel, these gaskets are suitable for a wide range of temperatures from -20ºF to 450ºF. They last up to five times longer than conventional solid PTFE gaskets so your system maintenance is greatly reduced and they offer a host of other advantages including:

	Minimal thermal expansion or cold flow creep
	No bacteria entrapment or obstruction of flow
	Non-stick surface
	Compliance with USDA, 3A and ASME-BPE standards
	U.S. Pharmacopoeia Class VI-XXII certification

Smart Gasket
The Smart Gasket™ is the ideal device for checking and validating the sterility of your ultra-pure system. Installed between two sanitary flanges, the Smart Gasket™ can be used to hold spore challenge test strips, meter fluids or withdraw samples. Easy to install and use, it seals completely without a deadleg when the gasket is compressed. Available in sizes from 1/2" to 4", the Smart Gasket™ features:

	Choice of 1, 2, 3 or 4 internal ports
	Compatible with the industry leaders of sanitary clamp connections
	USDA, EPDM, Platinum-Cured Silicone, Viton® and other gaskets

Torque-Rite®
Eliminate over-tightening or under-tightening of surface gaskets with the Torque-Rite®. Installed along with a Perfect Surface Gasket, the unique Torque-Rite clamp makes a "click" when it is properly tightened. Further tightening will not exert any more pressure, so there's no danger of tearing or extruding the gasket. Applying proper torque to the gasket is critical to the integrity of your system since gaskets that are too tight or too loose can lead to contamination or bacteria entrapment. Constructed of 440C stainless steel, the Torque-Rite® also offers:

	A manual override feature for emergency tightening
	Compatibility with Buna, Silicone, Viton®, EPDM, Criti-flex, Teflon®, TEF-STEEL® or Teflon® Envelope Perfect Surface Gaskets
	USDA, 3A and US Pharmacopoeia Class VI-XXII approval
