An improved sealing apparatus and associated methods are disclosed herein. The sealing apparatus includes a housing defining a center axis, an alignment element positioned around the center axis, and a sealing element fixedly attached with the alignment element. The alignment element has first and second protrusions extending toward the center axis. The sealing element has a third protrusion extending toward the center axis. The alignment element is made of a first material with less elasticity than a second material of which the sealing element is made.

A method of manufacturing a gasket material may comprise inserting a polymer sheet into a press, and pressing the polymer sheet with a mold comprising opposing arrays of protrusions to define interconnected sealing ridges surrounding an array of indentations on each major surface of the polymer sheet. A gasket material may comprise a polymer sheet comprising a first major surface and a second major surface, the second major surface opposing the first major surface. Interconnected sealing ridges may define an array of indentations on the first major surface of the polymer sheet. Additionally, interconnected sealing ridges may define an array of indentations on the second major surface of the polymer sheet, substantially symmetric to the first major surface.

A kammprofile gasket is provided. The kammprofile gasket forms a flow aperture into which an object, such as a strainer or orifice plate, may be machined into the gasket to provide additional functionality. The gasket has a core material with a sealing material overlaying a portion of the core material such that a seal is formed between opposing flanged surfaces. The core material may be machined such that a base plate for an orifice or a plurality of support beams extend into the flow aperture. The plurality of support beams may provide support for a filter or strainer coupled upstream to the core material. The base plate may provide an inclined surface, such as a cone, to an orifice where the cone functions to direct excess flow away from the orifice to self flush.

Wearable rubber parts for fluid handling systems include a four layer structure, wherein the inner most layer of the four layer structure is a polyurethane layer. The polyurethane can be millable polyurethane. The polyurethane used in the inner most layer can be produced by reacting diisolcyanate with a polyester and/or polyether polyols and a chain extender. The wearable rubber part can be an expansion joint, a pinch valve, or a hose.

An extreme temperature gasket material capable of withstanding temperatures in excess of 850 F. is provided. The extreme temperature gasket generally includes an inorganic filler, an inorganic fiber, and an organic binder. In some embodiments, the inorganic filler is from 75 to 90 wt % of the gasket material and can include submicron-sized talc particles. The inorganic fiber can be from 5 to 20 wt % of the gasket material and can include silicic acid fiber. The binder can be a latex emulsion and can be present in the gasket material in the range of from 1 to 5 wt % of the gasket material. The gasket material also can include additives, such as flocculant and defoamer. In some embodiments, the amount of organic material present in the gasket material is limited to less than 5 wt % of the gasket material.
