PLAST-O-MATIC

About PLAST-O-MATIC

PLAST-O-MATIC is a US-based manufacturer of thermoplastic valves, pressure regulators, and flow control components for corrosive and ultra-pure liquid handling. The company's product line is built around PVC, CPVC, PTFE, polypropylene, and PVDF wetted materials, with seal options including FKM, EPDM, Viton, and Buna-N. These products are used in chemical processing, water treatment, semiconductor wet benches, plating lines, and laboratory fluid systems where metal components would corrode or contaminate the media. 3G Electric supplies the PLAST-O-MATIC range as part of its industrial flow-control catalog, with more than 160 SKUs available for direct quotation and global dispatch.

The PLAST-O-MATIC portfolio covers several functional categories. Pressure relief valves, including adjustable back pressure and antisiphon models, protect piping from overpressure in corrosive service. These are available in body sizes from 1 inch to 3 inches with FNPT connections, and set pressures are field-adjustable. Gauge guards isolate pressure instruments from aggressive or clogging process media using PTFE or Viton diaphragms, preventing gauge damage and maintaining readable pressure indication. The gauge guard line includes models with PVC bodies, Buna-N O-rings, and 1/2 inch process by 1/4 inch gauge connection patterns. Other product families include pressure regulators, bypass valves, and specialty flow control devices, all sharing the same thermoplastic construction philosophy.

Technical buyers selecting PLAST-O-MATIC components typically evaluate body material, seal elastomer, end connection type and size, and temperature range. For example, a PTFE antisiphon relief valve may be rated from 32°F to 140°F, while PVC-bodied units with FKM seals suit a broader chemical compatibility envelope. Many PLAST-O-MATIC products carry ISO 9001:2015 certification, and country of origin is typically the USA, though this can change by batch. 3G Electric lists manufacturer part numbers, connection sizes, seal materials, and media suitability for each SKU so that maintenance and procurement teams can cross-reference existing installations without ambiguity.

3G Electric supports the PLAST-O-MATIC line by holding or sourcing the full range of catalog items, from common relief valves to less frequently stocked gauge guard variants. The distributor provides part-number-level search, specification filtering, and quotation support for plant engineers and maintenance managers who need to replace or specify components in corrosive-fluid systems. Because 3G Electric ships globally, buyers are not limited by region when sourcing these thermoplastic valves and accessories. The catalog includes both standard and OEM part numbers, and 3G Electric can assist with identifying equivalent or alternate materials when a specific elastomer or body material is required for a given chemical service.
