Gaskets, Washers, O-Rings and Silicone Tubing for Industrial Sealing Procurement

Sealing parts, gaskets, washers, O-rings, rubber parts and silicone tubes for maintenance and custom replacement use.

Category Procurement Overview

Source Sealing, Gaskets & Rubber Parts with the Right Specification

This category supports maintenance buyers, distributors and equipment OEMs sourcing PTFE gaskets, washer kits, rubber O-rings, sealing washers, silicone gaskets, tubing and refill assortments. A reliable sealing quotation starts with the physical dimensions and service condition: provide ID, OD, thickness or cross-section, material preference, hardness, temperature, media, pressure and quantity. PTFE is selected for low friction and broad chemical resistance in gaskets and washers. NBR is a common oil-resistant choice for general O-rings and sealing washers. EPDM, silicone and FKM routes can be considered when water, heat, weathering or stronger chemical requirements drive the material choice. Standard kits provide an economical maintenance or resale option, while custom parts can be die cut, machined, molded or packed as labeled assortments. Clean die-cut edges, controlled flash and appropriate carton separation help protect the parts during distribution. Share a drawing, existing sample or part number with the operating conditions to match the compound and dimensions to the actual seal rather than only a nominal size.

Procurement FAQ

Sealing, Gaskets & Rubber Parts Buyer Questions

How should buyers choose PTFE, NBR, EPDM or silicone?

PTFE is used for low friction and broad chemical resistance; NBR for general oil resistance; EPDM for water and weathering; silicone for flexible high- and low-temperature sealing.

What dimensions are needed for a sealing-part quotation?

Provide ID, OD, thickness or cross-section, material, hardness, media, temperature, pressure, quantity and a drawing or sample where available.

Can O-rings and washers be supplied as maintenance kits?

Yes. Standard or custom assortments can use labeled bags, compartment boxes, refill packs, color coding and OEM carton labels.
