Lamons NSF-61 Certified Sheet Gasket 1-1/16 ID x 2-1/4 OD

Description

Product Overview

The Lamons NSF‑61 Certified Sheet Gasket (model CRG1082.750.125.150) is engineered for demanding applications that require both high temperature resistance and strict drinking‑water safety standards. Constructed from proprietary compressed fiber sheet (SSS) technology, the gasket delivers mechanical strength comparable to elastomeric grades while eliminating the risk of contaminant leaching. Its nominal dimensions of 1‑1/16″ ID by 2‑1/4″ OD fit a wide range of standard fittings, and the package measures 15 × 13 × 2 inches, weighing just 2 lb for easy handling. Certified to NSF‑61, the gasket has passed rigorous testing for prohibited substances and leachable contaminants, ensuring it meets the highest safety criteria for potable water systems.

Usage

This gasket excels in environments where both temperature and pressure are critical. Ideal for use in chemical processing, food and beverage production, and municipal water treatment, it maintains continuous service at 500°F (260°C) and up to 1160 psi (80 bar). The maximum service rating of 752°F (400°C) and 1595 psi (110 bar) provides a safety margin for occasional peak loads. Install the gasket between flanged connections, pump housings, or valve seats where a reliable seal is essential. Its compressed fiber composition resists compression set, ensuring a consistent seal over long service intervals, reducing maintenance downtime.

Why Choose Us

Lamons brings over three decades of sealing expertise, and this gasket reflects that heritage. The NSF‑61 certification is not merely a label; it represents a comprehensive review of formulation, testing for prohibited substances, and verification that no harmful leachates enter drinking water. Our manufacturing process employs precision compression of high‑grade fibers, yielding a sheet that outperforms traditional rubber or silicone gaskets in both durability and chemical resistance. Each batch undergoes independent laboratory testing to confirm temperature, pressure, and contaminant specifications, providing confidence to engineers and procurement specialists alike.

FAQ

Is this gasket suitable for direct contact with drinking water?

Yes. The gasket is NSF‑61 certified, meaning it has been tested and approved for use in potable water systems without leaching harmful substances.

What temperature range can the gasket handle continuously?

The gasket is rated for continuous service up to 500°F (260°C). It can withstand short‑term spikes up to 752°F (400°C) without loss of integrity.

Can the gasket be reused after removal?

While the compressed fiber material is highly resilient, re‑use is not recommended for critical sealing applications. For optimal performance, install a new gasket each time the joint is opened.

What pressure ratings apply to this gasket?

Continuous service pressure is rated at 1160 psi (80 bar). The maximum pressure rating, suitable for brief excursions, is 1595 psi (110 bar).

How does the NSF‑61 testing process work?

When a gasket is submitted for NSF‑61 testing, the formulation is first reviewed for prohibited substances. It then undergoes laboratory analysis to detect any contaminants that could leach into drinking water, ensuring compliance with strict health standards.
