Spiral Wound Gasket 4″ x 600# 304SS Inner Ring – Sterling Seal Supply

Description

Product Overview

The Sterling Seal and Supply API 601 9000IR4304GR600 spiral wound gasket is engineered for demanding industrial applications where reliability and performance are paramount. Constructed with a 304 stainless steel inner ring, the gasket provides a corrosion‑resistant barrier that maintains its integrity even in aggressive chemical environments. The flexible graphite filler, wound in a precise metal‑to‑filler ratio, offers exceptional compressibility and resilience, allowing the gasket to accommodate flange imperfections while delivering a tight seal.

Designed to meet API 601 specifications, this gasket supports a pressure class of 600# and is compatible with both flat‑face and raised‑face flanges. Its dimensions—4 inches nominal pipe size, 600# pressure rating, and a 304SS inner ring—make it an ideal choice for a wide range of hydraulic and pneumatic systems, including oil and gas pipelines, chemical processing equipment, and high‑temperature heat exchangers. The product dimensions of 9.02 x 8.98 x 0.47 inches and a lightweight of 1.04 pounds facilitate easy handling and storage.

Manufactured by Lamons, a trusted name in sealing technology, the gasket carries the Lamons model number 9000IR4304GR600 and has been available since April 3, 2014. Its best‑seller rank of #27 in the Spiral Wound Gaskets category underscores its popularity among professionals seeking dependable sealing solutions. The inclusion of a 304 stainless steel inner ring ensures compatibility with a broad spectrum of media, from water and steam to aggressive solvents, while the graphite filler tolerates temperature extremes from -320°F to 850°F.

Installation is straightforward: the gasket’s spiral wound design allows for quick placement and removal without the need for specialized tools. Its flexible nature reduces the risk of flange damage during assembly, and the gasket’s durability minimizes the frequency of replacements, delivering long‑term cost savings. Whether used in new installations or retrofits, this gasket provides a seamless fit and reliable performance that meets or exceeds industry standards.

Usage

This spiral wound gasket excels in environments where temperature fluctuations and pressure variations are common. It is particularly well‑suited for high‑temperature steam lines, oil‑field equipment, and chemical processing plants where the combination of corrosion resistance and thermal stability is essential. The gasket’s ability to handle temperatures as low as -320°F makes it viable for cryogenic applications, while its upper limit of 850°F ensures performance in high‑heat scenarios such as furnace exhaust systems.

Engineers and maintenance professionals often select this gasket for sealing flanged connections in pumps, compressors, heat exchangers, and reactors. Its compatibility with both flat‑face and raised‑face flanges simplifies inventory management, allowing a single part number to cover multiple flange configurations. The 4‑inch pipe size aligns with standard piping dimensions, facilitating integration into existing systems without the need for custom machining.

In addition to industrial settings, the gasket is appropriate for marine applications where exposure to saltwater and fluctuating temperatures can degrade lesser sealing materials. Its robust construction also makes it a reliable choice for offshore platforms, where maintenance intervals are limited and equipment reliability is critical. By providing a consistent seal under demanding conditions, the gasket helps prevent leaks, reduce downtime, and protect personnel and equipment.
