Wolar Industrial, Inc.

What Wolar Industrial, Inc. does

Wolar Industrial, Inc. is a Houston, Texas-based manufacturer of industrial sealing gaskets, founded in 1992 and self-identified as the largest ring gasket manufacturer in the United States. Its product portfolio is built around two core platforms: Ring Joint Gaskets (RTJ), precision-machined in oval, octagonal, RX, BX, SBX, and specialty variants for pressures up to 20,000 psi; and Spiral Wound Gaskets (SWG), constructed with V-shaped metal windings and graphite filler to ASME B16.20. The company holds API 6A and API 17D certifications, which qualify its products for wellhead, Christmas tree, and subsea applications, and it markets a proprietary K-Series line with APX-2 graphite coating under the Kam Gaskets and K-RTJ sub-brands.

The business serves oil and gas (upstream, midstream, downstream), refining, petrochemical, power generation, mining, machinery manufacturing, defense, and pipeline transportation customers, with named end-users including BP, Chevron, ExxonMobil, Shell, Marathon Petroleum, Valero, Phillips 66, LyondellBasell, Dow, Eastman Chemical, Northrop Grumman, Nucor, and Enterprise Products Partners. Revenue is generated through quote-based, transactional sales of custom-manufactured gaskets, distributed via a combination of direct enterprise sales and a 20+ authorized distributor network spanning the USA, Canada, Singapore, and Thailand. The company is privately held, minority-owned, and 100% family-owned by the Lara family under second-generation leadership since 2024, with 11-50 employees and no disclosed institutional capital.

Products and services

• Ring Joint Gaskets (RTJ) Precision-machined ring gaskets designed to seal in high-pressure (up to 5,000 psi) and high-temperature applications, compliant with API 6A and ASME B16.20 standards. Available in oval or octagonal cross-sections with materials ranging from Soft Iron to exotic alloys like Hastelloy and Inconel. Originally manufactured to meet oilfield pressure requirements and now used in refining and downstream applications.
• Spiral Wound Gaskets (SWG) Spiral Wound Gaskets feature V-shaped metal windings with flexible graphite filler, manufactured in accordance with ASME B16.20 standards. They are the industry standard for sealing in refining and petrochemical applications, available in versions with inner and outer rings (SWGI) or outer ring only (SWG). Designed for effective and sustainable sealing in the toughest applications.
• K-Series Gasket (Kam Gaskets) High-performance RTJ gasket with octagonal core configured to ASME and API standards, featuring serrated sealing surfaces lined with APX-2 graphite for superior sealing at lower stresses than conventional RTJs. Includes fire-safe features and third-party validation. Marketed under the Kam Gaskets sub-brand.
• BX-Series Gasket RTJ gasket designed exclusively for 6BX flanges and 16BX hubs, rated for higher pressures from 5,000 to 20,000 lbs. Pitch diameters are slightly larger than flange pitch diameter, forcing gasket to seal on outside angles first, then inside angles as flange is bolted down.
• RX-Series Gasket RTJ gasket engineered for pressures up to 5,000 PSI, interchangeable with R-oval or R-octagonal rings on API 6B flanges. Designed for 6B flanged blowout preventer (BOP) stacks.
• Wellhead Connector Gasket Gasket for type wellhead connectors and blowout preventers (BOP), available in AX, CX, VX, VGX, and VT-style profiles. Manufactured in various material grades and alloys with required coatings.
• Rubber Coated Gasket Gasket crafted from precision-machined low-carbon steel with rubber molding applied using a 300-ton electric compression press. Ideal for hydrostatic testing at pressures exceeding operational ranges.
• IX Gasket Gasket manufactured in accordance with NORSOK Standard L-005 as an alternative to ASME flanges with reduced weight and smaller dimensions. Available in various material grades, alloys, and coating types.
• ClampLock Seal Ring Metal-to-metal seal ring for compact flange applications requiring leak-free sealing under extreme temperatures and pressures in a lightweight, small-footprint design.
• Custom Gasket Manufacturing Services Custom gasket manufacturing services including special materials (Hastelloy, Inconel), rubber-coated gaskets, and specialty products such as Blind RTJ, Spacer RTJ, Lens Rings, and IX Gaskets. Available in various material grades, alloys, sizes, and configurations per customer specifications.
