One-Minute Overview

Klingersil C4430 Gasket is built for a leak-tight ASME B16.5 face at 150LB with a Klingersil C4430 sealing element.
G10 sleeves and washers with ZPS come as a matched set, so the insulating stack stays concentric under bolt load.
The 2 Inch bore and gasket OD are checked against the flange drawing before cutting.
Final thickness and bolt circle are confirmed per inquiry.

Leak tightness on an isolated flange depends on even compression, not just on the gasket material. Klingersil C4430 Gasket combines a Klingersil C4430 element with G10 sleeves, washers and ZPS for ASME B16.5 flanges rated 150LB. The assembly is sized for 2 Inch so the sealing face and the insulating hardware work as one stack.

Name: Klingersil C4430 Gasket 2 Inch
Material: Klingersil C4430
Compound: aramid fibre with a nitrile binder
Standard: ASME B16.5
Size: 2 Inch
Pressure: 150LB
Complete with: G10 sleeves and washers with ZPS
Note: Full dimensions and bolt pattern are confirmed per inquiry.

Confirm the facing type, the 150LB class and the ASME B16.5 bolt circle first, because they determine how much compressive area is available. Then check that the Klingersil C4430 element suits the medium and that the 2 Inch bore leaves the pipe clear; an undersized bore creates turbulence and erodes the gasket edge.

Degrease both faces and remove all old gasket material before setting the element concentric with the bore. Bring bolts up in three cross-pattern passes, pausing between passes so the Klingersil C4430 element creeps evenly. Fit sleeves square under the washers, then recheck torque after the first thermal cycle when gasket relaxation is greatest.

FAQ

Q1. What causes an isolated flange to leak after start-up?

Uneven bolt load, a damaged ASME B16.5 face or a sleeve seated at an angle are the usual causes. Creep of the Klingersil C4430 element after the first heat-up also relaxes the joint, which is why a torque recheck is specified.

Q2. How is the 2 Inch bore verified before the gasket is cut?

Compare the pipe ID and the ASME B16.5 flange drawing with the proposed bore. The opening must clear the pipe without leaving an unsupported gasket ring that could extrude at 150LB.

Q3. Why must the whole insulating stack come from one kit?

Mixing G10 sleeves and washers with ZPS from different sources changes stack height and compression. A matched set keeps every bolt equally isolated and lets the Klingersil C4430 element compress uniformly across the face.

Q4. How long will production take?

Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders get a confirmed date per order, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is at the moment you order.
