FAQ
Frequently Asked Questions
When to specify 4SH instead of 4SP?
Specify 4SH when you need higher working pressure at larger inside diameters. For example, at 2" ID, both 4SP and 4SH are rated 16 MPa, but at 3/4" to 1" 4SH is engineered for a different pressure envelope. Always compare the published pressure table for your exact size.
What is the burst pressure of 4SH?
Burst pressure is at least 3× working pressure for every size. For 3/4" 4SH the working pressure is 42 MPa, giving a minimum burst pressure of 126 MPa.
Can 4SH be used in sub-zero environments?
Yes. The NBR compound is rated for -40°C. For arctic applications below -40°C, specify a low-temperature cover compound. Always confirm with our engineers for continuous cold-climate service.
Do you provide crimped 4SH assemblies?
Yes. Send your BOM with hose size, length, fitting part numbers and crimp specification. We ship proof-tested, labelled assemblies ready for installation.
What is the lead time for 4SH hose?
Standard sizes typically ship in 15-25 days. Custom compounds, MSHA-style covers or large container quantities may extend lead time. Confirm with our sales engineer when ordering.
