Type H 3/8''-5/8'' Oil Saver Rubber with 55 Shore Hardness for Wireline Equipment

Product Description

Type H Oil Saver Rubber is a replaceable line-wiping element used in a matching surface oil saver housing. The Type H range covers the 3/8–5/8-inch line-size references in black rubber, with the bore specified for the actual line. Confirm the exact line diameter, rubber bore and outside profile against the housing drawing. The element helps wipe carried-out fluid. Specify any pressure-service requirements for the complete oil saver assembly and follow its manufacturer instructions.

Type H 3/8–5/8-inch Oil Saver Rubber: Specify the 55-Shore Requirement

The existing hardness reference is 55 Shore without a stated scale or tolerance. Confirm the required scale, target and tolerance with the selected compound before manufacture. Black color does not identify the compound grade or prove chemical resistance.

For Type H replacement enquiries, record the exact line diameter, housing maker and part number, rubber drawing or sample, fluid composition and temperatures. The 3/8–5/8-inch range is a line-size reference, not evidence that one bore fits every line. Keep Type H and GA order lines separate.

Type H Selection Features:

• Line Wiping: Match the rubber bore and profile to the actual line and housing; gas containment requires complete assembly documentation.

• Pressure Limits: Use the complete oil saver assembly rating and operating procedure; confirm pressure cycles, fluid composition and operating temperatures for the specified assembly.

• Type H Fit: Confirm the housing model, rubber dimensions and line diameter. Type GA and OSB are separate range references.

• Compound Selection: Provide the actual fluid, additives and service temperatures before selecting the rubber grade.

• Wear Inspection: Check bore wear, cuts and deformation according to the assembly maker’s maintenance procedure.
